a big thank you for having tracked down this bug, and having written
the patch. I am quite impressed that you dived into the arcanes of
deb to cudf encoding. The solution that you propose, that is creating
separate pseudo-packages for the vesionend and the unversioned virtual
package, is probably the only correct way to work around a bad design
decision in the cudf format (for which I am partly responsable).

I will have a deeper look at what the deb to cudf encoding looks
now over the weekend, and upload the fixed debian package very soon.

Cheers -Ralf.
