-- Information about the crash:
This usually happens if you delete sessions quickly. It's EASY TO CREATE. Create multiple sessions (say 10 or 20). Hold ctrl-d down...

I was NOT doing this for this crash, hence the new bug.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
