Exception when checking out another git branch

[gene-pavlovsky]

I have the current development branch running from Visual Studio (debug build).
I have a large Haxe project open.
Sometimes, when I switch to a different git branch, VS stops FlashDevelop with the following exception:

System.InvalidOperationException occurred
  HResult=0x80131509
  Message=Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.
  Source=<Cannot evaluate the exception source>

The message that FD is trying to show is "Inheritance loop detected between com.module.languageprovider.LanguageProviderModule and com.module.languageprovider.LanguageProviderModule."
By the way, the class is defined as class LanguageProviderModule extends Module implements ILanguageProviderModule (Module doesn't have a superclass), so I have no idea why would there be an inheritance loop. Needless to say, the project compiles and works.

As I told you yesterday, note that this kind of errors only appear during debugging. But yep, I guess this shouldn't trigger a circular reference.

Yes, I got that point.
I might be wrong, but it seems like this results in loss of functionality?
If I understand correctly, ASCompletion is trying to show a warning bar, but it never appears due to this exception.

I'm getting this exception when switching branches now:
