Video playback and thumbnails (partly) broken
I get this when trying to play videos in the new implementation in !110 (merged) (based on f83e8df6, I think):
[2021-02-22T09:10:53Z ERROR harbour_whisperfish::sfos::tokio_qt] unregisterSocketNotifier: fd=62
[2021-02-22T09:10:53Z ERROR harbour_whisperfish::sfos::tokio_qt] Could not register Fd: File exists (os error 17)
... and the video only plays if I set it to auto play; it plays once and then stops. Play/pause does not work even though the media player reports to be paused/playing. (I'm using the same QML stuff I used in File Browser, so I don't think it's a bug in my code.)
Also, the system thumbnailer fails to create thumbnails for video files but they are supported.
