Application that crashed: kontact
Version of the application: 4.3.5
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Input the password for PGP and waited as usual only to experience an immediate crash.  I was not running any intensive applications.  I've never experienced this particular bug before.  Not much else to say other than I clicked the link in my KDE favorites list and then entered the password and it failed right away.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
