Comment 6 for bug 109094

I took a backtrace of totem movie while it was hanging:

(gdb) where
#0 0xffffe410 in __kernel_vsyscall ()
#1 0xb704603b in semop () from /lib/tls/i686/cmov/libc.so.6
#2 0xb6cf55a1 in snd_pcm_dmix_open () from /usr/lib/libasound.so.2
#3 0xb6cf6287 in _snd_pcm_dmix_open () from /usr/lib/libasound.so.2
#4 0xb6cc4385 in ?? () from /usr/lib/libasound.so.2
...

(Beyond frame 4 is not interesting since insufficient debugging information was available to display procedure names, files, etc.)

Is the program trying to get exclusive access to a sound device? Should the software check to see if the device is already in use? Should it use a timeout?

Note that skype was running in another user account.
