Sounds like the sort of thing the third party repository at deb-multimedia.org does, and the 'dmo1' in the package name is a big clue that is the case here. Basically, every time a version of a library in deb-multimedia falls behind Debian you're likely to get some kind of breakage, because it has used the epoch number to fake up this 'I'm a higher version so install me instead of the of official Debian library'. If the OP is running Sid with deb-multimedia then this sort of thing is going to be a reoccurring problem. -- Tixy
