Description micu 2017-04-15 13:38:57 UTC

Application: kmail (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.10.8-200.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

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

Not 100% reproducible, but it happens quite often: After fetching and filtering my emails (I have a bunch of filters in place), using both POP3 and IMAP accounts, KMail is in this weird state of not reacting. I can click mails in the list, but they don't show up.

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