Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I was navigating with the mouse through the filter system. Alas, the filter system was becoming less and less responsive, thus necessitating further navigation. After the last two or so filters I created quit working entirely, so did the entire filter editing system. Sigh.


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