I think there is a conflict between debhelper and xfonts-utils here. update-fonts-alias requires package.alias to be in /etc/X11/fonts/X11R7/$dir, while dh_installxfonts still checks at the old place. That may be why the recent uploader still kept the file there (to get update-fonts-alias called, but unfortunately ineffective).
I've filed Bug #363482 against debhelper for this. Meanwhile, I've proposed ITA for this orphaned package. When dh_installxfonts is fixed, it should be solved in next upload. -- Theppitak Karoonboonyanan http://linux.thai.net/~thep/
