 In [https://bugs.launchpad.net/ubuntu/+source/totem/+bug/219281/comments/6
 this bug report], various users describe that Totem (and other
 applications using pulseaudio) becomes uninterruptible (cannot kill it
 even with -9) and uses 100% CPU. I also had this a few times and only a
 reboot solves it.

 The cause for this may be in pulseaudio, this is the last output before it
 happens:

 {{{E: thread-posix.c: Assertion 'pthread_setspecific(t->key, userdata) ==
 0' failed at pulsecore/thread-posix.c:194, function pa_tls_set().
 Aborting.}}}

 See also the attached stacktrace, which is originally from
 [https://bugs.launchpad.net/ubuntu/+source/totem/+bug/219281 this bug
 report].
