Comment 12 for bug 198957

Sorry, Soren, but what Nicolas is reporting _is_ this same bug, which has _not_ been fixed. I was just bitten by it myself. I see two possible, non-mutually-exclusive solutions:

1) Make libvirt-bin a "Recommended" package of virt-manager.
2) Make both libvirt-bin and virt-manager required dependencies of the ubuntu-desktop metapackage.

The second solution is the sledgehammer approach, but may prove beneficial in the long run. In any case, I strongly recommend the first solution above.
