Comment 1 for bug 16528

This happens to me when using Matlab.
If I close several windows using 'close all', kicker segfaults and doesn't
automatically get restarted.
I'm also using Hoary and the Kubuntu packages in Hoary.

(Rob, thanks for the nice testcase!)

I see the same trace as above, and many repetitions of the below message are
sent to stdout/stderr:

X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20
  Minor opcode: 0
