Comment(by benzea):

 GObject.threads_init() initializes the threading support inside pygobject.
 It is essential to call it when using threads.

 I expect that this could happen if webkit starts a thread and then calls
 back into python in a signal handler. I do expect that webkit is using
 threads internally, though it may be that it ensures that callbacks only
 happen from the main thread.

 I have cooked up a patch against gobject introspection, haven't even
 compile tested it yet though. Basically the idea is to not do any python
 calls when GObjects are destroyed after the python interpreter has been
 finalized.
