-- Information about the crash:
I use Gmail via IMAP.  I left my computer unattended for a while.  When I came back, there was a message telling me that the connection to gmail had been lost and would be re-established automatically if possible.  I clicked OK.  Shortly afterwards, I clicked "Check Mail" a few times, without apparent effect.  Then I quit Kontact and this crash happened.

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