Bug#1120577: libgdk-pixbuf-2.0-0: Error loading XPM image loader: Image type “xpm” is not supported

[Jeremy Bícha]

Note that Ubuntu 26.04 LTS and Debian will probably switch gdk-pixbuf
to glycin soon which does not support xpm loading. We'll track that
detail in a separate bug connected to https://bugs.debian.org/1116981

Thank you,
