Fixes errors not caught in review.

Seems not to work in KDE

Seems to run, but when using KDE desktop, get the following message:

flatpak run org.gnome.Evince

(evince:2): GdkPixbuf-WARNING **: 07:59:33.914: Cannot open pixbuf loader module file '/app/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory

This likely means that your installation is broken. Try running the command gdk-pixbuf-query-loaders > /app/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache to make things work again for the time being.

Seems to work, but get error messages as indicated below:
