MediaPortal stopped due to an exception Type 'TraktPlugin.TraktAPI.DataStructures.TraktMovieSummary' (1 Viewer)

Terra · August 21, 2017

Hi there,

Frequently my MePo crashes when I resume from windows standby or when I start it.
I found this in the log files last time, seems some issue with Trakt?
It is not really re-produceable with any steps, just happens sometimes and wanted to report it.

Logs attached!

Code:

Thanks, I will look into it and add some guards to prevent such a scenario from happening.

catavolt · August 22, 2017

Can confirm it here since some weeks - MP even crashes when e.g. hovering over the Trending Movies/Series in BasicHome

Sebastiii · August 22, 2017

Hi Guys

I'm getting most often getting a MP crash when going back to home when i'm from myvideo playlist.

Code:

Application: MediaPortal.exe

I have try to look if something can be catch on MP code, but i didn't find what, so not sure if something can be done on Trakt code side

ltfearme · August 22, 2017

Hi Sebastii, Im not sure the trakt plugin will be able to catch that, could you add some extra null checks in ClearCachedAllocatorImages() ?

Sebastiii · August 22, 2017

Sure

It happen randomly but has it happen often

Sebastiii · August 22, 2017

Added :

C#:

public static void ClearCachedAllocatorImages()
    {
      if (_cachedAllocatorImages != null)
      {
        foreach (String sTextureName in _cachedAllocatorImages)
        {
          if (sTextureName != null) Flush(sTextureName);
        }
        _cachedAllocatorImages.Clear();
      }
      _cachedAllocatorImages = null;
      _cachedAllocatorImages = new List<string>();
    }

Null check for sTextureName -> if (sTextureName != null) Flush(sTextureName);

Sebastiii · August 22, 2017

I'm just getting the crash

It seems to be because in line :
foreach (String sTextureName in _cachedAllocatorImages)
There is no _cachedAllocatorImages (count is 0) and then it failed here, let's try by adding :

C#:

public static void ClearCachedAllocatorImages()
    {
      if (_cachedAllocatorImages != null)
      {
        if (_cachedAllocatorImages.Count > 0)
        {
          foreach (String sTextureName in _cachedAllocatorImages)
          {
            if (sTextureName != null) Flush(sTextureName);
          }
        }
        _cachedAllocatorImages.Clear();
      }
      _cachedAllocatorImages = null;
      _cachedAllocatorImages = new List<string>();
    }

What do you thing @ltfearme ?

Sebastiii · August 22, 2017

And a json error, maybe related to the first post :

ltfearme · August 22, 2017

I think that last error is because it could not find the Newtonsoft.Json dll. I plan on removing that dependency as its only used for the calendar functions which I plan to update.
