Still happening every time with Kontact 5.0.2 & KDE Frameworks 5.15.0.
Comment 2 Martin Tlustos 2016-01-15 13:47:01 UTC 
Same here. Crash does not occur in kmail standalone Kubuntu 15.10, Kontact 5.0.2, Frameworks 5.15.0

Kontact crash log
Comment 4 Chris Samuel 2016-10-13 00:37:54 UTC 
Crash still happening with Kontact 5.2.3.

I've even blown away my Akonadi DB in the last month to try and fix it to no avail.
Comment 5 Erik Quaeghebeur 2018-12-10 09:47:48 UTC 
Is this still happening?
Comment 6 Martin Tlustos 2018-12-10 11:58:57 UTC 
Works for me in kontact 5.9.3

I'm currently in the middle of moving hemispheres so my PC is in a container on a ship somewhere, but it was still happening just before it was packed away.

Good travels!

Can you report back once you're settled and have the time to test a more recent version than you last reported about?

Thank you!

> recent version than you last reported about?

OK, I've just tonight upgraded to 18.10 and installed their Kubuntu PPA backports and upgraded to their most recent Plasma and KDE packages.  So far so good!

Needs more testing than just starting and exiting 3 times, but no crashes so far.

Kontact version 5.8.3, KDE Frameworks 5.52.0

All the best,
Chris
Comment 10 Chris Samuel 2019-02-19 02:25:08 UTC 
All still good - I'm closing this as fixed, thanks you!
