Application: kmail (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.14.83-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

KMail was apparently trying to reload my IMAP mailboxes, but didn't manage (another IMAP client had no such trouble). So I shut KMail down and restarted. Upon restart, it crashed.

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