"Here is logs about crash. Mp is in normal use: zapping, using teletex,
some channels might have had normal dvb subtitles.

I hope logs have catched some clues, as these few things that dev's wanted us to
look at in first page of this therad are quite new, i mean Mp has been more stable
about a month ago. Now this crash happens totally without any certain behavior i do.
Sometimes it crashes just after i've rebooted and started to watch first channel after reboot.
Sometimes it happens only after using teletex and few hours later. No pattern how to make it happen.

I'm sorry not been able to help more. My system specs are just below my avatar.


regards

EDIT:

Just happened again. And log shows the same as attaced log:

2010-02-07 12:48:10.601994 [ERROR][Teletext Updater(36)]: MediaPortal: Unhandled exception occured
2010-02-07 12:48:10.674998 [ERROR][Teletext Updater(36)]: Exception :confused:ystem.ArgumentNullException: Value cannot be null.
Parameter name: image
at System.Drawing.Graphics.FromImage(Image image)
at TvLibrary.Teletext.TeletextPageRenderer.RenderPage(Bitmap& pageBitmap, Byte[] byPage, Int32 mPage, Int32 sPage)
at TvPlugin.TvTeletextBase.Redraw()

at System.Threading.ThreadHelper.ThreadStart_Context(Object state)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
at System.Threading.ThreadHelper.ThreadStart()

That's killing my Mp

I looked a code a bit and i don't understand how that image variable could be null as it is created few lines above hmm...

Maybe if this RenderPage is called twice in a row before previous call has not ended."
