Description Jens 2024-09-08 13:36:00 UTC 
SUMMARY: see $SUBJECT.

Console output when starting appimage and choosing "Integrate and start application":

 $ ./digiKam-8.5.0-20240908T100120-Qt6-x86-64-debug.appimage 
 ERROR: appimage_shall_not_be_integrated : Entry doesn't exists: org.kde.digikam.desktop
 AppImageLauncher error: appimage_shall_not_be_integrated() failed (returned -1)
 ERROR: appimage_is_terminal_app : Entry doesn't exists: org.kde.digikam.desktop
 AppImageLauncher error: appimage_is_terminal_app() failed (returned -1)
 ERROR: appimage_register_in_system : Entry doesn't exists: org.kde.digikam.desktop

There is no more logging even with export QT_LOGGING_RULES="digikam*=true".
Also, double clicking the appimage freezes the complete desktop (Wayland) for >10 seconds until the appimage starts.

This started happening some versions ago somewhere in July (I think). I don't remember the exact build, unfortunately.

Other appimages integrate correctly, e.g. Subsurface https://subsurface-divelog.org/current-release/ (scroll all the way down for the appimage) which seems to be a showcase app for the Appimage concept. So this does not seem to be a KDE Neon bug.

STEPS TO REPRODUCE
1. Download appimage x86-64 with or without debug enabled)
2. Start it in KDE Neon
3. Choose "Integrate and start" when asked

OBSERVED RESULT
Error see above. The appimage is moved to ~/Applications though, so part of the integration actually happens.

EXPECTED RESULT
Appimage should integrate and start.

SOFTWARE/OS VERSIONS: KDE Neon 6.1 22.04 (x86_64), digikam 8.5 2024-09-08 Appimage,
Comment 1 Maik Qualmann 2024-09-08 14:03:02 UTC 
This could be a problem with the AppImageLauncher, see Bug 490657.
If you start the AppImage without integration in a terminal, does it run without problems?

Comment 2 Jens 2024-09-08 18:05:41 UTC 
It works, but none of the apps that Digikam tries to start will launch.
For example, Firefox (browser) to report bugs, or "open in file manager" context menu item, all do nothing.
If I run them in the console I get something like this:

Dolphin:
unknown: No language dictionaries for the language: "en_US"
unknown: Could not find the Qt platform plugin "wayland" in ""
/usr/bin/dolphin: symbol lookup error: /usr/bin/dolphin: undefined symbol: _ZN11KIconEffect10toDisabledER7QPixmap

Firefox:
unknown: Could not find the Qt platform plugin "wayland" in ""
XPCOMGlueLoad error for file /usr/lib/firefox/libnss3.so:
/usr/lib/x86_64-linux-gnu/libnssutil3.so: version `NSSUTIL_3.101' not found (required by /usr/lib/firefox/libnss3.so)
Couldn't load XPCOM.

All apps run normally when *not* started from within Digikam.
This may be a library preloading issue. Can we fix this for the Appimage?
Comment 3 Maik Qualmann 2024-09-08 18:20:23 UTC 
Try the Qt5 AppImage from here:

Comment 6 Jens 2024-09-10 18:42:32 UTC 
Qt5 appimage shows the same issue when starting or integrating.
But starting apps from within Digikam - e.g. Dolphin file manager or Firefox or VLC - works here, as opposed to in the Qt6 version.

However, the Qt5 build does not have the KDE styling.

With the December 3rd release of Digikam pre-8.6.0, this again worked today on my machine.
Integration went as planned.

Thank you :-)
