Long tail of wrong translation language, how to correct?

[Andika Triwidada]

Dear translation admins,

There are several strange translation suggestion for Indonesian. For example:
https://translations.edge.launchpad.net/ubuntu/hardy/+source/kde-guidance/+pots/guidance/id/87/+translate
This translation comes from different language (Hungarian?),
definitely unrelated to Indonesian.

It will appear as an annoying suggestion for translations like in:
https://translations.edge.launchpad.net/ubuntu/karmic/+source/gdm/+pots/gdm/id/206/+translate
and many other places.

I think this is related to bug #133315:
https://bugs.edge.launchpad.net/ubuntu/+source/kde-guidance/+bug/133315

What is the best way to prevent those wrong suggestion from keep reappearing?

Thanks
