Guys, any clue as to what is causing this crash? Were there any
threading changes in 2.6.6 that may have triggered this? Thanks.
Joe

This looks like a threading problem with Python. I'm seeing a crash
(with next to no details) that seems to stem from Python and threads.
I'm copying python@ here.
Python guys, after an upgrade to 2.6.6, starting audio/rhythmbox results
in a crash. Gdb reports:
0x0804b327 in main (argc=1235131264, argv=0x2) at main.c:330
330 pyg_begin_allow_threads;
(and nothing else, weird)
This function is a macro defined in pygobject.h to be:
#define pyg_begin_allow_threads \
G_STMT_START { \
PyThreadState *_save = NULL; \
if (_PyGObject_API->threads_enabled) \
_save = PyEval_SaveThread();
#define pyg_end_allow_threads \
if (_PyGObject_API->threads_enabled) \
PyEval_RestoreThread(_save); \
} G_STMT_END
Python has been built with default threading (but no pth). Counting
myself, three users have reported this problem on RELENG_8.
