[Bug] MediaPortal crashing intermittently when interacting with the TV Guide (1 Viewer)

[Holzi]

1. Go to TV Home, Full EPG, click on a channel, click on any show.
2. Mouse click TopBar "<", "<", then "X" to exit MePo, I get the crash.

Can reproduce a crash with these steps too.

Holzi,

what MePo version are you using? If you use windows Event Viewer to look at Application errors do you get the following type of error?

Faulting application name: MediaPortal.exe, version: 1.5.0.0, time stamp: 0x5245685c
Faulting module name: KERNELBASE.dll, version: 6.1.7601.18229, time stamp: 0x51fb1116
Exception code: 0xe053534f
Fault offset: 0x0000c41f
Faulting process id: 0x%9
Faulting application start time: 0x%10
Faulting application path: %11
Faulting module path: %12
Report Id: %13

I added the info from the crash dumps for MePo 1.5. Not sure how useful this info is or what other debug info is needed to find the real problem.

Can someone can make a video ?

Here is a Video attached: https://forum.team-mediaportal.com/...-with-the-tv-guide.122994/page-2#post-1046747

Steps to reproduce (with keyboard):

1. Go to TV guide
2. Select a channel
3. Select a program of this channel which gets you to the program info screen
4. Hit ESC two times
5. Crash

Bleh thanks i already downloaded this video lol. That's what happen when i'm lost memory

Zzzz, now it gets strange! Today I can't reproduce the crashes anymore... Using MP 1.6.0.

But I am seeing this behaviour now:

It doesn't crash here but I can't select a program anymore if I go back (the point where it crashes by Holzi). It only moves the time for and back >_>

...which is the same is what I see.
I've tried over and over and over to reproduce this problem, but I can't.

EPG didn't work correctly for me and that's maybe why I can't reproduce it. I have see strange error in Log so I have try to attach vs to TV service and quickly TV service crash. So it's another issue but related to EPG. I'm not at home right now put can provide log later and surely on another thread forum

Good news
I can reproduce the crash lol (no fix) but the crash is here lol

It seems that it doesn't crash always @ the same place.

hmmm seems random, i have change skin to test (SMP / DW) -> no crash
Back to titan -> no crash ....

Ahah found something :
When it crash, it happen after doing ESC for me and it run in a loop :

[2014-01-03 18:33:53,224] [Error  ] [MPMain  ] [ERROR] - OnMessage cntTarget.OnMessage:GUI_MSG_SETFOCUS

I have added this log line :

                  GUIControl cntTarget = GetControl(message.TargetControlId);
                  if (cntTarget != null)
                  {
                    // recalculate visibility, so a invisible item that is becoming visible
                    // becouse the previous component is no longer focused can be focused
                    // mantis issue #1755
                    //UpdateVisibility();  //Bav: reverting change, because it is creating a nonfocused status, when a focus is switching from one control to the other
                    Log.Error("OnMessage cntTarget.OnMessage:{0}", message.Message);
                    cntTarget.OnMessage(message);
                  }

So now is to know why it does that

 

[Sebastiii]

It seems that i can reproduce the crash with Titan only but can't be an issue on MP that Titan trigger.
For some obscure reason, when going back to previous windows, it goes here : (if (Disabled || !CanFocus()))
And then MP try to focus on all guide item (that too much and then lead to the crash)
So it's maybe a property set or not set on skin files but skin and me, we are not friend

    {
      if (message.TargetControlId == GetID)
      {
        switch (message.Message)
        {
          case GUIMessage.MessageType.GUI_MSG_SETFOCUS:

            // if control is disabled then move 2 the next control
            if (Disabled || !CanFocus())
            {
              int controlId = 0;

              switch ((Action.ActionType)message.Param1)
              {
                case Action.ActionType.ACTION_MOVE_DOWN:
                  controlId = NavigateDown;
                  break;
                case Action.ActionType.ACTION_MOVE_UP:
                  controlId = NavigateUp;
                  break;
                case Action.ActionType.ACTION_MOVE_LEFT:
                  controlId = NavigateRight;
                  break;
                case Action.ActionType.ACTION_MOVE_RIGHT:
                  controlId = NavigateLeft;
                  break;
              }

              if (controlId == 0)
              {
                controlId = Navigate((Direction)message.Param1);
              }

              if (controlId != -1 && controlId != GetID)
              {
                FocusControl(WindowId, controlId, (Direction)message.Param1);
              }

              return true;
            }

            Focus = true;
            return true;
