I ran into similar problems with a joinable thread. It could have been a 
fault in my code, I wasn't sure, but somehow WX tried to force kill the 
thread instead of just waiting for it. This workaround solved it:

Create the thread as wxTHREAD_DETACHED instead of wxTHREAD_JOINABLE, and 
add two wxSemaphores. When the thread has finished its work, it signals 
semaphore 1 and then waits for semaphore 2.

Instead of Wait()ing for the thread, the main thread waits for semaphore 
1 and then signals semaphore 2. The thread object should not be deleted 
in this case (it will clean up itself).
I guess a wxCondition would have worked too.
