Comment 6 for bug 1214218

I can give another example (and not the first one I've seen).
The group is qbittorrent, but apt, libudev1, apt-utils, libapt-pkg6.0, libsystemd0 all aren't related at all.
qbittorrent comes from a PPA (http://ppa.launchpad.net/qbittorrent-team/qbittorrent-stable/ubuntu).
There are non-grouped libudev1:i386, libsystemd0:i386 and I had the impression before that the occurrence of both a native and a i386 package may be involved in the mis-grouping.
