Bug#1032224: pkg-perl-tools: Behaves weirdly if there are two different upstream tags for the same version

[Axel Beckert]

Package: pkg-perl-tools
Version: 0.75
Severity: minor

The upstream of dhcpy3d accidentially tagged the 1.2.3 release as both
"v1.2.3" and "1.2.3" without "v".

My debian/gbp.conf says clearly:

  [DEFAULT]
  upstream-vcs-tag=v%(version)s

Nevertheless "dpt import-orig" on the 1.2.2 git checkout fails as
follows:

% dpt import-orig

Note that weird line break between "'1.2.3" and "v1.2.3'".

Temporarily worked around it by running "git tag -d 1.2.3" in a second
shell in the right moment. :-)
