Crash report attached.
From terminal "digikam" starts OK and also "digikam -qwindowtitle %c". If I create a shortcut to the desktop I get the attached crach report.

Comment 4 caulier.gilles 2016-10-10 15:46:27 UTC

I crash in X11 API where with Wayland this must never happen of course. X11 API is used here to get screen color profile from X server if this is one set by end user.

Q : Which system did you use to run Wayland ?

Can you reproduce the problem using digiKam Linux AppImage bundle ? The last
bundle is available at this url:

Comment 9 caulier.gilles 2016-12-25 14:08:36 UTC

Any feedback with current 5.4.0 AppImage Linux bundle ?

Comment 10 caulier.gilles 2016-12-27 11:51:05 UTC

I just tested digiKam 5.4.0 with Gnome+Wayland under Mageia6 (Cauldron).

It do not crash. Color Management have been enabled of course.

digiKam still compiled with XCB support through KF5 framework. It do not use Wayland directly. It slow, as a gateway work in background to support XCB based application.

Using Wayland directly is another story, more complicated to handle, as Qt5+KF5 Wayland support need to be enabled. This will be for later, when this environnement will be more dispatched everywhere.

So for me the current situation work.

To Miku84:

I want to be sure. 

Can you run a KDE application on your system (a based one, installed with a package), and go to Help/About dialog. Copy the contents of Version tab in this thread. 

Thanks in advance

Comment 12 caulier.gilles 2016-12-27 11:56:21 UTC

Note : KF5 5.29 and Qt 5.6.2 is used here under Mageia6 Cauldron.

Comment 13 miku84 2017-01-13 19:43:01 UTC

I have tried it with digikam 5.4, KF 5.29, Plasma 5.8.4 and it crashed as before, but only from the desktop shortcut.
From terminal digikam -qwindowtitle %c" is working.

Comment 14 miku84 2017-02-24 21:12:16 UTC

I managed digikam to work with
QT_QPA_PLATFORM=xcb digikam 
command. Plus is, it needs D-bus registration feedback.
