Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1) "release 1"
Qt Version: 4.5.2
Operating System: Linux 2.6.31-rc9-7-default i686
Distribution: "openSUSE 11.2 Milestone 7 (i586)"

What I was doing when the application crashed:
I use googlemail with IMAP in KMail. KMail just crashed when I switched folders (from spam to inbox). Before switching I deleted them spam mails, it might be that the mails had not jet been deleted (I switched the folder right after pressing the del key).

I have quite a lot mails in my inbox, almost 20000, perhaps that is important.

This is the second time I have a crash when switching folders, but the first time I couldn't get a good backtrace.
