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

Maybe there is a race condition somewhere, perhaps try making a copy of _cachedAllocatorImages before iterating over it?

 

[Sebastiii]

Ok
Try to see if it's possible or if i can do it

 

[ltfearme]

Maybe a lock as well if there is a race condition, hard to answer without doing a full code review.

About the JSON, for this one, it's my fault i was debugging MP and didn't have this dll in root !!!!!
About the code review :
MediaPortal-1/GUIImageAllocator.cs at master · MediaPortal/MediaPortal-1 · GitHub

Damien, another lead maybe for MP crash in Trakt : in \Trakt-for-Mediaportal\TraktPlugin\GUI\GUIExtensions.cs

I can't see why or maybe like you said put a lock.

I can probably remove those extension methods now since the plugin doesn't officially support MP 1.1 anymore anyway.

Maybe that will help, probably easy for you to compile your own trakt plugin to test, find all instances where it calls that extension method (or just in the dashboard class) and replace with the native call.

 

[Sebastiii]

Ok
Can you give me an example ?
For this :
facade.SetCurrentLayout(TraktSkinSettings.DashboardActivityFacadeType);

Thanks.

 

[ltfearme]

Replace:

facade.SetCurrentLayout(TraktSkinSettings.DashboardActivityFacadeType);

with

facade.CurrentLayout = GUIFacadeControl.Layout.List;

and

facade.SetCurrentLayout(trendingSettings.FacadeType);

with

facade.CurrentLayout = GUIFacadeControl.Layout.Filmstrip;

The layout types are loaded from skin settings, so its important to realise that this might not work for the skin you use. It needs a few tweaks.

@Sebastii, I committed some changes to remove the old backwards compatibility code. It will be interesting to know whether you get the same crash still.

 

[Sebastiii]

Will try it thanks, i didn't take the time to change on my side so big thanks
