I can reproduce this crash then every time I restart kmail. Once I switch to one of the other predefined folders (outbox, sent items etc.) and then to one of the inbox-subfolders, things seem to work.

Look at bug 178718
Gentoo wasn't applying the Qt patch to fix this issue. Try updating your Qt version to the latest in Gentoo.

Comment 3 Dennis Lichtenthäler 2009-01-31 14:32:15 UTC

Thanks. The new version was hitting the tree while I was still trying to reliably reproduce this bug. Upgrading to qt-gui-4.4.2-r2 fixed the crashes.
