Echoing Adi Roiban's thoughts on tangerine-icon-theme, either it doesn't ship copyright info, or vrms doesn't like CC-BY-SA. Regardless, I use Tango, but apparently I can't remove this without taking out ubuntu-desktop. Is it possible to drop this from Depends to Recommends? :D
Using Intel graphics (i945), Intel wireless with iwl3945. No restricted-modules packages installed (in fact, I can't find those packages in the karmic archives anyway).
I hate unrar, and wish unrar-free worked a little better or that people would stop using the rar format.
If the font situation improves in the future, mscorefonts won't be needed. Perhaps it has improved already; I'll admit to having not tried other font sets.
Updates: Removed ttf-mscorefonts in favor of ttf-liberation, and liking it so far. Also filed 427401 regarding tangerine-icon-theme.
I've also realized that I'm using Adobe Flash, but it's their own amd64 library that I manually installed.
OK, elephant in the room.
Unrar-nonfree is only needed if you download a lot of illegal stuff off the internet.
You need to just stop that :P
Hehe, that may be true for a good amount of people. However, I've had to use it for project work that others have been sending me packed with the commercial WinRAR. They refuse to listen to my comments about using another format. :(
