Bug 144959

Version:            (using KDE KDE 3.5.6)
Installed from:    Gentoo Packages
OS:                Linux

When pressing "+" to goto next unread message and no unread messages where in the same folder KMail crashed with the following backtrace (KMail was running from within Kontact), so far I've been unable to reproduce the crash:

Using host libthread_db library "/lib/libthread_db.so.1".
