+Subject: disable automatic portal launching
+
+in Qt6 (and the KDE patch collection for Qt 5) genericunixservices will
+internally attempt to probe the portal tech early on in the app life
+cycle. this causes the protal system to launch app and then crash
+because we aren't actually providing a fully functional session. instead
+opt out of this altogether
+
+(cherry picked from commit fc24321541f6f65b7d1aac89cd82336ffd53e1a0)
