Thanks everyone for confirming the bug. I don't think there's any more need to report it.
If you have any other useful information, please provide it.
Otherwise, please don't turn this bug report into a rant.
This is the first ubuntu release with multiarch enabled, so it's not that far-fetched that there will be problems with non-core tools (such as aptitude, as helpful as it might be).
Shahar, it's very likely that all of the multiarch bugs are due to the same problem, yes.
