suspend inhibit no longer working

[jsch]

Listening to podcasts using gnome-podcasts (flatpak) was working fine until last weekend. It no longer prevents the system from suspend.
The log shows

Code:

xdg-desktop-por[1103]: A backend call failed: Inhibiting other than idle not supported

On Friday everything was fine, next time I started podcasts (on Monday) the system went to sleep after 5 minutes.
Between Friday and Monday ~40 packages were updated.
Any idea where to start hunting this issue?
