Bug#734267: [Debian add-on] setting distribution only works when distro is known

[Eduard Bloch]

Package: vim-common
Version: 2:7.4.052-1
Severity: normal

When I try to set the distribution via the Changelog menu in gvim, it
fails when the head line looks like this:

foo-pkg (0.7.25-1) UNRELEASED; urgency=low

But it works when there is some known release branch like "frozen"
instead of UNRELEASED. This looks like a regression, I remember having
used this feature to change "UNRELEASED" many times in the last years.

Regards,
Eduard.
