Task request or is it needed for another software in our repo?

It's a little unclear what the process is for submitting a package that hasn't already been requested, but I argue this is needed for GdkPixbuf-based image viewers to use WebP files.

This also would resolve T8793, which was marked as Wontfix due to libwebp not including this.

Any update on the possibility of this being accepted?

a usysconf trigger should be added to update the gdk-pixbuf cache after install
/usr/bin/gdk-pixbuf-query-loaders --update-cache

Successfully tested with eom

Should I simply add that command after the install section or is there a specific way to do this? I wasn't able to find any info on this in the packaging documentation.

Sorry, just saw that you haven't receive an answer to this. What @kyrios123 meant is that we should add a new trigger to usysconf itself, which will allow it to detect changes to pixbuf loaders and update the gdk-pixbuf cache after package installations

I've made a pull request on that repo to add this. You can find it here.
