Bug 443644

Bug report from reporting tool.

can you run it under gdb and get a more useful stacktrace ?
is pulseaudio running when this happens ?

After much debuginfo-install-ing, I got:

I have no idea if pulseaudio is running or not.  How do I tell?

ps ax | grep pulseaudio 

should tell you

ps ax | egrep pulse
 2550 ?        Sl     0:00 /usr/bin/pulseaudio --log-target=syslog
 2555 ?        S      0:00 /usr/libexec/pulse/gconf-helper
 2721 pts/1    S+     0:00 egrep pulse

Looks like it's running.

Lennart, any idea why i should be NULL here ?

This happened in old version of pavucontrol when no devices where configured in
PA. I fixed that a while ago. Please update pavucontrol.

Still crashes with latest rawhide.

Confirmed on a livecd of todays rawhide - it still crashes.

Hmm, it appears you put 0.9.6 into cvs, but never built it, Lennart. Building it
now.
