On my system (Debian Lenny AMD64),
gnome-panel seems to act up now and again. I've not found a way to force it to happen, but it seems to be related to launching processes. Basically, I launch some process, and I see 1 core max itself out, and the taskbar freezes. I
pkill gnome-panel, the taskbar reappears, and everything is ok. If I don't notice it, eventually my entire computer freezes and I have to hard boot.
How would I go about getting some kind of information on why this is happening that could help me or developers? Is there a debug build or something I could run?
