Comment 14 for bug 182923

Yes, I've only experienced the problem at startup. While I am never hibernating I cannot speak for it.

I have some more information: the CPU usage seemed to start even though I had an internet connection at the time. When I tried to reproduce the bug the other day I disconnected my internet, restarted mail-notification and the bug did NOT show up. I seems that this bug is not related to whether actually having a functional internet connection or not - am I experiencing another bug?

Another thing, there actually seems to be a timeout to the CPU usage for me. I did not time it, but maybe after ~10 minutes CPU usage goesx down to normal.

Jean-Yes: I followed your instructions to get gnome debug symbols but gdb is still unwilling to give any symbols for gnome packages. I've paused the program multiple times and the backtrace given seems to be the same.
