The obvious way is to ask libglade mainteiners to fix this issue. They
can ask Niels to remove libglade from repo and rebuild all dependent
packages. I don't see this as a huge problem, rather as business as
usual for repository mainteiners. We just need to fix this and move on.

If community would decide to introduce some checks into builder we can
do that.
I already have 2 candidates - check for categories and this one.

Well, many things have rough edges :) Repository full of not buildable
packages without sources is much worse than this issue, IMHO.
