Bug 232335

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 2.6.32-3-686-bigmem i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
In a yahoogroups.com-style email list digest, I clicked on a link to an attached pdf file. The application-chooser prompt appeared. No MIME-type was specified. I chose konqueror. The attachment opened properly, and kmail crashed.

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