Not really. Have you tried getting a C stacktrace using gdb?  The only obvious reason for blocking is the GIL: if for some reason the main thread doesn't release the GIL at some point you'll get a hang in the secondary threads. That's pretty unlikely though given that the secondary thread does some work before it hangs.

Debugging would be easier if you had a smallish sample program (a dependency on PyGUI would be fine)
