Hi! While working on the “reproducible builds” effort [1], we have noticed that some packages failed to build reproducibly because the order of icons listed in dh_icons output varies depending on the order of files on the filesystem. The attached patch modifies dh_icons to sort the icon list, resulting in a stable order in postinst and postrm files. This allows more packages to build reproducibly.

Subject: [PATCH 2/3] dh_icons: output icon list in a stable order
We now sort the icon list in order to guarantee a stable output.
This was preventing some packages to build reproducibly.
