I stumble on error mesages like the following if I try
to restart the application "Jitsi 2.6-5390" quickly.
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
java: xcb_io.c:179: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
How should such a software surprise be resolved?
