Description Bruno Friedmann 2019-04-01 14:35:13 UTC 
Application: kmail (5.10.3)

Qt Version: 5.12.2
Frameworks Version: 5.56.0
Operating System: Linux 5.0.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: When I delete several mail or move several mail at once with multiple select and or keyboard shortcut m there's a hang (messages become greyed) but nothing change, and the interface freeze, you can click on other folders but nothing happend except akonadi or kmail crashes.

This behaviour is increasing since the last few weeks, becoming more and more frequent.
Database used PostgreSQL 10.7 (libpq is 11.2)
baloo is disabled by balooctl disable as it doesn't work.

Running akonadictl fsck or vacuum help sometime but not always.
All email parts are stored inside the database.

The crash can be reproduced every time.

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