Public bug reported:
Binary package hint: kdebase-workspace
I monitored remote machine with ksysguard (via custom-command ssh)
When the machine got offline, the tree with list of sensors/hosts was
drawn incorrectly.
After clicking a bit on that tree I got it to crash:
Application: System Monitor (ksysguard), signal: Segmentation fault
