nemo-compare is broken due to glycin and gdk-pixbuf

Im using nemo as main file manager on cachyos (Archlinux) for years and never had any problems.

As mentioned in title nemo-compare stops working a few weeks ago. Comparing two files results in a glycin/gdk-pixbuf error. Here is the Treceback after starting nemo in debug mode an comparing two files; the glycin error is at the end:

After downgrading glycin to version 1.2.3 and the proper dependency gdk-pixbuf2 2.42.12 the extension is working as indented.

Reproduce nemo-compare on CachyOS/Arch with the glycin and gdk-pixbuf2 versions described, then inspect meld/actiongutter.py where icon loading fails. Compare behavior with glycin 1.2.3 and gdk-pixbuf2 2.42.12; done means file comparison works without the loader or GTK errors.
