[Python-apps-team] Bug#790052: pelican: trying to overwrite '/usr/share/man/man1/pelican-themes.1.gz', which is also in package python-pelican 3.6.0-1

[Axel Beckert]

Package: pelican
Version: 3.6.0-2
Severity: serious

Dear Maintainer,

pelican has the vrong version in its Breaks and Replaces header which
makes the installation fail if python-pelican was installed before
(i.e. upon a python-pelican upgrade):

[…]
Unpacking pelican (3.6.0-2) ...
dpkg: error processing archive /var/cache/apt/archives/pelican_3.6.0-2_all.deb (--unpack):
 trying to overwrite '/usr/share/man/man1/pelican-themes.1.gz', which is also in package python-pelican 3.6.0-1

[…]
E: Sub-process /usr/bin/dpkg returned an error code (1)
[…]
dpkg: dependency problems prevent configuration of python-pelican:
 python-pelican depends on pelican; however:
  Package pelican is not installed.

dpkg: error processing package python-pelican (--configure):
 dependency problems - leaving unconfigured
[…]
Errors were encountered while processing:
 python-pelican

Current headers:

Replaces: python-pelican (<< 3.6.0-1)
Breaks: python-pelican (<< 3.6.0-1)

What the headers should look like:

Replaces: python-pelican (<< 3.6.0-2~)
Breaks: python-pelican (<< 3.6.0-2~)
