[Gtk-sharp-list] Strange Tree Model behavior (Multi-Threading)

[James Talton]

I was seeing weird behavior on Windows with GTK and getting random
exceptions.  From some other discussions on this mailing list I did the
following:

Glib.Thread.Init();
Gdk.Threads.Init();
Application.Init();

Gdk.Threads.Enter();
try
{
    Application.Run();
}
finally
{
    Gdk.Threads.Leave();
}

See if that fixes your problem.  If it does, please let us know.

If it does not fix your problem, put a breakpoint where you call GetValue,
open up the threads window and make sure your calls are being done on the
main thread.
