[Giacomo Mulas]

Package: gnome-tweaks
Version: 49.0-1
Severity: normal

Dear Maintainer,

gnome-tweaks fails to start on my gnome wayland session on sid, with the following python stack trace:

gmulas at capitanata:~$ gnome-tweaks

TypeError: GioUnix.DesktopAppInfo.get_filename() takes exactly 1 argument (0 given)

I had not tried to use it for a while, so I don't know exactly since when this problem arised. It looks very much like some underlying python api was changed under its feet and it was not updated to match it. Please let me know if there is some additional information I can provide, or test I can perform, to ease solving this.

Thanks in advance, best regards
Giacomo Mulas
