Version:           1.9 (using KDE KDE 3.5.0)
Installed from:    Ubuntu Packages
OS:                Linux

In all 3.5 variants I've tried (jriddel's kubuntu packages), deleting multiple mails from my inbox usually causes kmail to crash.
Same behaviour experienced when deleting from a search folder (that searches my inbox). I have not tried other folders.
This never happened in 3.4.x.


It's not deterministic, I'll usually get away with selecting 3-6 mails and deleting them, but if i select 30 or so it's pretty sure to crash. Sometimes just deleteing one will do it.

I always use shift-delete.

The backtrace shows lots of functions that look like they relate to search folders - maybe it's a race condition causing the folder search code to look up deleted messages?
