Bug#884704: libgtksourceviewmm-3.0-doc: fails to upgrade from 'testing' - trying to overwrite /usr/share/doc/libgtksourceviewmm-3.0-dev/NEWS.gz

[Andreas Beckmann]

Package: libgtksourceviewmm-3.0-doc
Version: 3.18.0-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'testing'.
It installed fine in 'testing', then the upgrade to 'sid' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/#overwriting-files-and-replacing-packages-replaces

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package libgtksourceviewmm-3.0-doc.
  Preparing to unpack .../87-libgtksourceviewmm-3.0-doc_3.18.0-2_all.deb ...

   trying to overwrite '/usr/share/doc/libgtksourceviewmm-3.0-dev/NEWS.gz', which is also in package libgtksourceviewmm-3.0-dev:amd64 3.18.0-1

cheers,

Andreas
