Application that crashed: kmail
Version of the application: 1.12.90
KDE Version: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-ARCH x86_64

What I was doing when the application crashed:
I was reading a message from nf2 on kde-core-devel, then clicked +, which moved to the next message from nf2.  Then it crashed, apparently while checking nf2's PGP signature.
