-- Information about the crash:
- What I was doing when the application crashed:
I had selected multiple IMAP mailboxes to show the messages in all of them simultaneously. After trying to de-select one of them (with ctrl-click), kmail crashed.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
