Application: kmail (1.13.7)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-686-pae i686
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:

I quit kmail while it was checking e-mail..  Then I remembered I had to send another e-mail.  So I started kmail up again immediately.  When I started kmail up again, it was still downloading e-mails over my gmail IMAP account.   Then I got a bunch of pop-ups complaining about a connection problem. Clicked through those and then kmail crashed.

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