Bug#803528: Stack trace for glxgears

["Kingsley G. Morse Jr." <kingsley@loaner.com>]

Here's a stack trace from when glxgears hangs

    (gdb) bt

It seems to me to be hard to be certain without
symbols, but I see somesimilarities with the stack
trace from kdenlive.

Also, note that no Qt code is involved.

Thanks,
Kingsley
