+Subject: [PATCH] Fix KPluginSelector KCMs missing their metadata on plugin
+ loading
+
+For the KWin KCMs we need the full metadata, because we read the
+plugin keyword.
+
+Without the X-KDE-ConfigModule key, plugins used to create a symlink
+in the kservices5 folder to their metadata, which then goes through the
+legacy code path we would read all the metadata.
+This includes the plugin keyword.
+
+When consumers would this key, but have an old KWin version which
+used the KPluginSelector class and a kcmutils version which reads X-KDE-ConfigModule, but does not
+include this bugfix, the plugin keyword will be empty and thus the config
+files can not be located.
+
+This makes it hard to fix the loading on kcmutils < 5.91, but keeping the
+code working with KWin < 5.24.
+
+To test this, you should check out KWin 5.23 and kcmutils master.
+Fox example https://github.com/nclarius/tile-gaps/ will then fail
+to load it's config. With this change included, it should load properly.
