So, there are several templates, that need to be changed...
These templates can be hidden, as the packages were moved to Universe:
https://translations.launchpad.net/ubuntu/lucid/+source/ubuntu-wallpapers - The gutsy-wallpapers package seems to be in Universe now - I may be wrong, IIRC there is a wp with this name... btw, I can't see any translated wallpaper names anyway - this might be worth a bugreport
https://translations.launchpad.net/ubuntu/lucid/+source/libgda3
https://translations.launchpad.net/ubuntu/lucid/+source/computer-janitor - This has now two templates, computer-janitor seems to be obsolete
https://translations.launchpad.net/ubuntu/lucid/+source/ubuntu-docs - bug #414035 says, programming chapter was dropped
https://launchpad.net/ubuntu/lucid/+source/compiz-fusion-plugins-extra
https://translations.launchpad.net/ubuntu/lucid/+source/abiword
https://launchpad.net/ubuntu/lucid/+source/gpaint
https://launchpad.net/ubuntu/lucid/+source/gnome-pilot-conduits
https://launchpad.net/ubuntu/lucid/+source/xsane
https://launchpad.net/ubuntu/lucid/+source/kdelibs
These templates might need greater priority, to show up earlier in the list:
https://translations.launchpad.net/ubuntu/lucid/+source/gimp
Is the gimp-tips template intentionally not among the other gimp templates, as it is a translation of an xml file, thus not used currently? If not, then it should be bumped, if yes, perhaps it can be hidden...
https://translations.launchpad.net/ubuntu/lucid/+source/xorg - failsafexinit is important, see bux #335678
https://translations.launchpad.net/ubuntu/lucid/+source/gbrainy - will be installed by default
https://translations.launchpad.net/ubuntu/lucid/+source/grub2 - at last... the boot loader is translatable :)
https://translations.launchpad.net/ubuntu/lucid/+source/indicator-me - another member of the indicator-* family
https://translations.launchpad.net/ubuntu/lucid/+source/kubuntu-docs - here kubuntu-docs-basic-commands and kubuntu-docs-development need to be bumped, while it seems kubuntu-docs-index has a too large priority
https://translations.launchpad.net/ubuntu/lucid/+source/ubiquity-slideshow-ubuntu - there are some new kubuntu templates, I suppose they will be quite visible :)
https://translations.launchpad.net/ubuntu/lucid/+source/simple-scan - will be installed by default
There are two templates named texinfo, from two different packages:
https://translations.launchpad.net/ubuntu/lucid/+source/texinfo
https://translations.launchpad.net/ubuntu/lucid/+source/texlive-bin
I have no idea what to do with these... perhaps nothing, but they look strangely similar:
https://translations.launchpad.net/ubuntu/lucid/+source/texlive-bin/+pots/texinfo/hu/+translate?batch=50 - this has no Hungarian translations, but there is a suggestion for every string from the other template.
