Application that crashed: kmail
Version of the application: 1.12.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-0.slh.1-sidux-686 i686
Distribution: Debian GNU/Linux 5.0.3 (lenny)

What I was doing when the application crashed:
i was connected to a wifi network without internet when KMail told me "mailserver connection timeouted" and crashed. Well, in the same time I was connecting to another wifi and _maybe_ KMail crashed when the connection to internet got established.

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