Version:            (using KDE 4.2.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I am using disconnected IMAP with kmail on Debian unstable with kde packages from experimental (4.2.1-2). After renaming more than one folder, kmail crashes on sync. In detail I named those folders from 1,2,3,4 to 01,02,03,04 because of their order. I am willing to provide additional info on request.

Greetings,

Ferdinand
