I'm a Gloria user who upgraded from Felicia yesterday. I have been using the mythbuntu repros in Felicia a long time without any problem.
After the upgrade I experienced this problem:
https://bugs.launchpad.net/ubuntu/karmi ... bug/341898
According to the bugreport this should be solved in mythbuntu. However it's not solved in Linux Mint, I have tried to add superm1:s PPA but it doesent find any newer version then what's already installed on my system and refuses to upgrade.
