Seems like some recent KDE upgrade has broken the System Monitor applet. (Dunno whether it's an Arch prob. or a KDE one.)

If you try to add the KDE System Monitor applet to the kicker taskbar for the first time, you get a crash with a signal 11. (There's some message about /etc/mtab that flashes first, but it disappears too quick for me to see it.) If you already HAD the System Monitor in kicker when you start up KDE it's even worse: kicker taskbar won't launch at all!

Someone posted a similar message on the forum about this but I didn't see any response. Any help appreciated.
This task depends upon

I found a little more information about this. Looks like it's dying because my /proc file system is not showing up in /etc/mtab:

[root@dlj2000 root]# cat /etc/mtab
/dev/scsi/host2/bus0/target0/lun0/part4 / reiserfs rw 0 0
none /dev/pts devpts rw 0 0
none /dev/shm tmpfs rw 0 0
tmpfs /tmp tmpfs rw,size=512M 0 0
usbfs /proc/bus/usb usbfs rw 0 0
/dev/scsi/host2/bus0/target0/lun0/part1 /boot ext3 rw 0 0
/dev/scsi/host2/bus0/target0/lun0/part3 /usr/share/music reiserfs rw 0 0
localhost:/var/lib/cfs/.cfsfs /var/cfs nfs rw,port=3049,intr,nfsvers=2,addr= 0 0

This is definitely the problem, because if I replace /etc/mtab with a symlink to /proc/mounts, the system monitor works fine. (That's not a workable solution, though, because "mount" keeps overwriting the symlink with a text file.)

modified the title and Assignee since this isn't really a KDE bug.

Okay, rc.sysinit now re-mounts /proc and /sys after / is RW. The entries are written to /etc/mtab properly.
