Comment 38 for bug 202089

I have earlier had problems with gnome-power-manager (and was told it was do to another bug - https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/196688), but yesterday I got a similar problem with pidgin:

The sound suddenly wasn't working, and I did a "killall pulseaudio", this used to help but didn't, so instead I did "ps aux | grep pulseaudio" and "kill -9 xxxx", and in the same moment I got a pidgin sound (like when you receive a message), even though it was at least an hour since I last got one. And then the system got slow, real slow, but i manage to open up gnome-system-monitor, and I saw that pidgin was eating up more that 500MB of my memory. Killing pidgin made the system run normal again.

It might be another bug again, but kind of weird it comes at the same as the gnome-power-manager did.
