[oS-EN] Can no longer mount phones in Thunar

Hi,

Since maybe two months ago, I can not mount my phone in Thunar, I get 
this error message (screenshot):



In the past, this solved itself by killing and restarting Thunar, or 
rebooting. I could not reboot for a month or so, till today. Machine 
freshly booted, and I get that message.

Dolphin connects just fine to the same phone.

This machine is Leap 15.6, so EOL, but I would appreciate clues.

Maybe interference from a previously opened and closed Dolphin window? 
But I do not see any "dolphin" process running with "ps afxu | less -S"
