        <pre>Let's try again: What are the backtraces of the other threads? Is any other
thread inside libxcb-code?

Also, does the application use libGL / libX11 from multiple threads? Is
XInitThreads() called at startup?

According to the only backtrace you provided, libX11 asks for a reply that we
don't have yet and some other thread "grabbed" the socket. Could you get a
debug build of libxcb and libX11 so that the backtraces provide more
information?</pre>
