Description Mathieu Jobin 2019-08-01 14:24:24 UTC

Application: kmail (5.10.3)

Qt Version: 5.12.2
Frameworks Version: 5.60.0
Operating System: Linux 5.0.0-23-generic x86_64
Distribution: Ubuntu 19.04

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

so I moved a few imap email to the imap trash
then to save some time, I selected the last 68 I wanted to delete and hit shift click
without waiting for too long, I right click on the trash wanted to empty it.

and kmail crashed at that moment

thank you

Kubuntu 19.04, Plasma 5.16.4, freshly rebooted after update
