I had clean install of KDE Neon distribution, added some applications (many, including wine), but I didn't touch any specific MIME config, OS was in the state as it was left by doing `apt-get install <apps>` after installation. When I tried the button "Launch Bug Report Wizard" in kmahjong, the `xdg-open http://bugs.kde.org/wizard.cgi` was ran, which ended by launching infinite number of wine instances (not sure about exact process name, wineservice maybe). After I did open firefox -> preferences -> set as default browser, the "Launch Bug Report Wizard" in kmahjong works as expected, and opens the bug report wizard in Firefox. So it looks to me like the KDE neon does not set any default browser, or the settings is invalid, but how the wine gets picked, and why infinite number of instances is being launched? I understand this is more like bad configuration, then code bug, but imagine unexperienced user watching his task list filled with infinite processes after he just did want to report some bug in some KDE app, maybe some config sanity check would be possible? Or reconfigure neon to set Firefox as default browser right after install?
Since you reported it for kdelibs 4.14, are you using the KDE4 version of kmahjongg? Please check using 'kmahjongg --version'.
$ kmahjongg --version kmahjongg 0.9 I just **guess** that this is more about the wine after-install configuration, eating up also html requests by default, as being able to reasonably process them (and nothing else in the clean neon volunteering for that). But I didn't verify (would take to install clean neon + wine and then to see what would xdg-open do? Maybe I may try that in virtual, if you confirm this may be of value). As being reported as kdelibs 4.14: not sure why, maybe I did select it by hand, or (more likely) it was already pre-selected when the browser opened.
That looks like the KF5 version, I think the old versions also added Qt version information in the output.
Could you retry with a current KF6?
