[gthumb-list] Search filter not working for tags

[Raphaël Marguet <raphael teugram fr>]

Hi,

I'm a new gThumb user and I tried using the filter rules to display all 
my pictures corresponding to a certain tag. No matter how I set the 
filter the search yields no results...

I found this 2 year old issue on gitlab : 
https://gitlab.gnome.org/GNOME/gthumb/-/issues/32
and was wondering if this is an isolated case (in this case any help to 
solve this would be appreciated), or if this is a known bug (maybe not 
bothering many users (?), or maybe devs just did not prioritize for any 
reason) ?

For me this feature is key in order to manage my pictures in different 
catalogs. Otherwise it would ask a lot of manual operations.

Thanks,
Raphaël
