Public bug reported: When I switch from one virtual desktop to another using the keyboard (i.e. ctrl-alt-left), sometimes it freezes and the X become completely irresponsive. I have to go to the console and kill metacity in order to recover it.
This is the backtrace I get if I attach to the metacity process once it hangs: #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:144 #1 0x00007f0d35227180 in pa_threaded_mainloop_wait () from /usr/lib/x86_64-linux-gnu/libpulse.so.0 #2 0x00007f0d3546c732 in pulse_driver_play () from /usr/lib/x86_64-linux-gnu/libcanberra-0.30/libcanberra-pulse.so #3 0x00007f0d3fe1a98e in ca_context_play_full () from /usr/lib/x86_64-linux-gnu/libcanberra.so.0 #4 0x00007f0d3fe1ad0f in ca_context_play () from /usr/lib/x86_64-linux-gnu/libcanberra.so.0 #5 0x0000000000445532 in ??
