SegFault in Deskbar

[jahaiku]

I have clicked into the icon-area in Deskbar where ProcessController lives to see the Processes but got this error.
The problem is that I was unable to reproduce and the backtrace in the started gdb only showed "????????" for all the lines of the bt.

This is the syslog for this SegFault:

vm_soft_fault: va 0x0 not covered by area in address space
vm_page_fault: vm_soft_fault returned error 'Bad address' on fault at 0x0, ip 0x0, write 0, user 1, thread 0x113
vm_page_fault: thread "menu_tracking" (275) in team "Deskbar" (74) tried to read address 0x0, ip 0x0 ("???" +0x0)

This is Haiku from Friday afternoon compiled with gcc4.
