Application: kontact (5.0.1) (Compiled from sources) Qt Version: 5.5.0 Operating System: Linux 4.3.0-rc2+ x86_64 Distribution (Platform): Slackware Packages -- Information about the crash: - What I was doing when the application crashed: After the Framework 5.15 update, when I change to LKML subfolder (about 100MB and 10K messages), kontact crashes. Same if I use Kmail2 only. I checked for some missing runtime dependencies, but I found none. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

This happens when I use breeze icon theme, if I switch to breeze-dark, it all works fine, but the messeages have no icon in the tree.
I am too seeing this crash. When I change the folder (or during the startup of the application), when the folder is loaded it displays dotted circles for the icon of the folder and there it crashes. I had only Breeze icon set before (when I observed the crash). With oxygen icon set, I dont see the crash.
I'm seeing the same crash as well. Changed the theme to Oxygen and the problem went away.

I can confirm the crash with KMail 4.14.3, KDE Development Platform 4.14.18 running on Plasma 5 desktop. The crash happens when a new folder is opened for which communication with akonadi is needed. When using the oxygen icon theme the crash does not happen. It happens with breezy and breezy-dark. There must be a pixmap missing and the absence is not handled nicely.

This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks, except possibly a Technology Preview version 5.0.x. Those Framework-based versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the opportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
