Description Gaetan Simard 2026-03-18 14:06:55 UTC

SUMMARY

When the "Help" button in a dialog (generally located on the bottom left part of dialog) is clicked, Digikam bring up some sort of built-in browser with these buttons (Back, Forward, Reload, Stop, Home, Desktop Browser). The browser form is displayed for a few seconds and then it disappear along with Digikam. The two associated digiKam-9.0.0-Qt6-x86-64.appimage processes are however still  running.
Restarting Digikam will create two new digiKam-9.0.0-Qt6-x86-64.appimage processes.

STEPS TO REPRODUCE
1. Clisk on Help -> Check for New Version...
2. Click on the "Help" button on the bottom left of the dialog
3. The built-in browser window with no content appears
4. After a few seconds (less than), the browser and Digikam windows disappear.

OBSERVED RESULT

No help content is displayed and Digikam window disappear

EXPECTED RESULT

The help content should have been displayed.

Which dialog exactly ? From a About plugin for ex ?

Comment 2 Gaetan Simard 2026-03-18 14:37:34 UTC

The problem appears from any location where I click on the "Help" button.
Here are a few locations where it happens;

* On the main screen of Digikam, 
   * Click on Help -> Check for New Version... -> Help
   * Click on Settings -> Help
   * Click on Tools -> Maintenance... -> Help
   * View -> Presentation... -> Help -> Online Handbook...

Each time help is requested, I  temporarily see what looks like a terminal window and it is replaced by a browser window that goes away (along Digikam) after a few seconds. I use "htop" to kill the Digikam main process and then I restart Digikam.

Comment 4 Maik Qualmann 2026-03-18 17:35:29 UTC

QWebEngine does not work in the digiKam-9.0.0 AppImage. See also Bug 517299.

Use the pre-release version of digiKam-9.1.0 from here:
