Version:           1.8 (using KDE 3.4.0, Debian Package 4:3.4.0-0ubuntu3 (3.1))
Compiler:          gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)
OS:                Linux (i686) release 2.6.9-1-686

How to re-produce:

1) Start dIMAP synchronization
2) While sync is in progress, delete a folder in your dIMAP tree
3) -> kmail crashes
