Application: kmail (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.4
Operating System: Linux 3.7.6-201.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

been using kmail happily for a few weeks but recently it will crash every time shortly after launch. Rendering it unuseable.

I've tried all of
aconadictl fsck
aconadictl vacuum
aconadictl restart
rm -rf ~/.kde/share/apps/kmail2

I'm at a loss as to how to get kmail to function again.

there are 2 IMAP servers used, one with only a few hundred messages and about a dozen nested folders and my main mail server, several hundred folders and a couple ten thousand messages.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
