Created attachment 105158 [details]
system log from start of application to finish

System log during digiKam start and crash.
Comment 2 caulier.gilles 2017-04-23 16:07:15 UTC 
digiKam 5.6.0 pre version do not crash under Wayland using Linux Mageia 6 Cauldron, with Plasma 5 desktop.

The backtrace do not show a specific code in digiKam which crash the application. It decent in-deep in Qt5 and the system libraries.

Also, if you can install debug symbols this can help to investigate.

Comment 3 caulier.gilles 2017-06-22 21:42:46 UTC 
digiKam 5.6.0 is now released and available as bundle for Linux, MacOS and Windows.

https://www.digikam.org/news/2017-06-21-5.6.0-release-announcement/

Can you check if problem still exists with this version ?

Thanks in advance

Problem still reproducible ?
Comment 5 Anton Latuha 2017-07-31 16:12:03 UTC 
Thank you, that waited some time.

Yes, it works now on the same Arch system. Close this.
Comment 6 Anton Latuha 2017-07-31 16:18:38 UTC 
I've closed bug.
Ok. Next time something major like this - compilation with debug symbols.
Thank you.
