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 i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I had just started Karmic and entered password to Wallet for access to WIFI and Kontact. I had not started any other applications. I launched Kontact email.
Viewing email, I tried to save a message (ctrl+S) was unsure about what folder to save to, so I cancelled save. Then I  saved again and Kontact crashed. 

However the crashes usually occur as I open Dolphin to look for a file. Could there be some issue between Kontact and file manager functions?
