-- Information about the crash:
Using kmail (inside kontact) I selected a message inside a thread.  Kmail was configured to group messages as threads.  I used the "delete thread" command (Shift Del) and kmail crashed.  In case it's useful information, the account is DIMAP.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
