STEPS TO REPRODUCE
1. load an image (jpg/png/...)
2. specify new size of the image
3. push ok

OBSERVED RESULT

It's probably a packaging problem.

Please try the official digiKam 7.3.0 pre-release Linux AppImage bundle available here :

I don't use digikam... only showFoto...
I escalated to opensuse support, as it was working before an update.

Comment 3 caulier.gilles 2021-05-06 19:50:23 UTC

With AppImage bundle, pass "showfoto" as argument to run it...

I'll check it tomorrow at the company, I have a laptop with openSUSE Leap 15.2 there, to see if there are any problems with the packages. OpenSUSE is actually always quite stable, but many users add extra package sources which then cause problems in the mix.

output

This is the output of the last resize attempt...

Comment 6 Maik Qualmann 2021-05-07 06:36:55 UTC

This is the debug output from the AppImage. You are working as the root user! There is an error message from QWebEngine because of the root user. QWebEngine may crash here.

The Showfoto-6.4.0 version of openSUSE Leap 15.2 (up to date) works here without any problems. For the test I also uninstalled the digiKam packages to see if there might be a package problem. No crashes when resizing and saving. Check your installed packages.

Comment 8 soundlord 2021-05-08 03:09:53 UTC

I already did uninstall/install the digikam and showfoto packages...
It is strange it worked on my root account since september 2020 without any issue.

I removed the libdigikamcore and digikam-plugins... I'm checking if the repositories are correct (to be cautious) with the LEAP team.

Comment 10 Maik Qualmann 2021-05-23 17:05:12 UTC

The cause is that QWebEngine (Chromium) cannot be executed as root user with activated sandbox. If you absolutely want to use digiKam as root user, you have to do the following beforehand:

export QTWEBENGINE_CHROMIUM_FLAGS=--no-sandbox

We strongly advise against using digiKam as the root user!
