Description Frank Danapfel 2017-09-15 09:46:39 UTC

Application: kmail (5.5.1)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.11-300.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- Selecting a e-mail to be able to see it in the preview pane

This has started after upgrading from Fedora 25 to 26. The system is using an Nvidia graphics card wit the Nouveau driver provided by F26 (the reason I mention this is that on F25 there was an issue with Kmail related to some locking routines of the mesa packages related to nouveau).

The crash can be reproduced every time.

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