I managed to recreate, in fact it happens everytime. I think it is an indicator-sound issue, as I can see the following difference in the indicator before and after the call:
BEFORE: dict entry( string "icon" variant struct { string "themed" variant array [ string "audio-volume-high-panel" string "audio-volume-high" string "audio-volume" string "audio" ] } ) AFTER: dict entry( string "icon" variant struct { string "themed" variant array [ string "" ] } ) The themed icon looks incorrect.
