Dock and Menubar bugs around

[Lumio]

Hi,
a friend of mine has Leopard on an elder PowerBook (4 years old). Right now she has problems with the Dock and the menubar. Both crashes continuously.
I tried to kill the Dock process, but when I do, it tells me, that there is no such process (even if I enter the processnumber).

So the console says me the following:

10.06.09 11:06:41 com.apple.launchd[68] ([0x0-0x1d01d].com.apple.dock[122]) Exited abnormally: Trace/BPT trap

Maybe someone can help me to find a solution for her. I think there is another way to solve this problem without reinstalling Leopard.

Thanks in anticipation.

Perhaps the Dock's database file is corrupted. Is the Dock even displaying? If not, this is probably the problem. The Dock database is located here: ~/Library/Preferences/com.apple.Dock.db where ~ is the home folder. Note that after you remove this file, you probably won't be able to empty the Trash - a logout and back in will fix that.

Well, the dock appears for a few seconds, but won't react on mouse-events. So after a few seconds, it disapears and restarts.
