Bug 269133

Application: kontact (4.4.10)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-6-generic x86_64
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I had just sent an e-mail and went to scroll through my current folder's e-mail list via the 2-finger scroll feature of my touch pad.  I have been noticing oddities when using contact and the 2-finger scroll, i.e. scrolling through a folders e-mail list also causes the account folder view to scroll.

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