Comment 4 for bug 248716

Only sauerbraten has been backported, not sauerbraten-data. This makes the backport uninstallable and is an annoyance if you had the hardy version installed.

Who is in charge of accepting packages into hardy-backports? It seems there is no quality control. This exact problem also occurred with alien-arena and openarena, which was just fixed today! I realise -backports is not officially supported, but I do wish a tiny bit more effort would be put into ensuring the packages are installable and have all their dependencies met.
