There is only one thread which manages to deadlock itself somehow. That
was also indicated by the message ("wait timed out in thread 0010,
blocked by 0000").

With winedbg I get for that thread:

Using another app, notepad, then the previous post. Because the gdb back
trace is slightly different, here is that as well:
