gPodder-r765-fix-sync-segfault.patch
gPodder randomly crashes when syncing and with the following error:
python: xcb_lock.c:33: _XCBUnlockDisplay: Assertion
`xcb_get_request_sent(dpy->xcb->connection) == dpy->request' failed.
Locking assertion failure. Backtrace:

python: xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) -
(dpy->request)) >= 0)' failed.
Multiple segmentation faults occurred; can't display error dialog
After some debugging with Justin, we concluded that it was happening because
gPodderSync is called from outside the main thread.
The attached patch *hopefully* fixes this nasty bug.
