Fixed. I've removed debian package and pasted "gdk-pixbuf" module from my yaml. Before I submit a PR, are you OK with compiling from source? I remember flathub had a policy of requiring only source-build modules, but I see they've changed it? I mean, should I submit it as is, or should I change it to copy .so from debian packages?

@konradmb I would very much like to have dependencies built from source, cf. #2. Looking forward to your PR!

I don't know how I haven't seen #2
