After upgrading (in-place) from 42.3 to 15.0, I notice entries like the
following for each and every notification that KDE plasmashell is showing to
me, in the systemd journal. That is annoying, escpecially as it shows the
complete notification text...

Jul 19 14:36:41 rofl plasmashell[10457]: Currrent active notifications: QHash()

Jul 19 14:36:41 rofl plasmashell[10457]:  New Notification:  "New email notify"
"From: bugzilla_noreply@novell.com\nSubject: [Bug 1101869] New: kdewallet once
more asking for explicit unlocking after login\nIn: Inbox" -1 & Part of: 0

Happens for notifications from both kmail + slack, and probably all...
