Bug#898056: gir1.2-anjuta-3.0: Differing versions break multi-arch support

[Francois Gouget]

Package: gir1.2-anjuta-3.0
Version: 2:3.28.0-1+b1
Severity: normal

Dear Maintainer,

This concerns Debian Testing and Unstable:

* For the amd64, arm64, armel, mips64el and s390x architectures only 
  version 2:3.28.0-1+b1 is available.

* For the armhf, i386, mips, mipsel and ppc64el architectures only version 
  2:3.28.0-1 is available.

* But gir1.2-anjuta-3.0 says that it breaks any version that's different. For 
  instance:
  Breaks: gir1.2-anjuta-3.0 (!= 2:3.28.0-1+b1)

Thus, because the amd64 and i386 architectures (for instance) are not available in 
the same version, they are not coinstallable, thus breaking multi-arch support.

Presumably at some point a new version will be available for all architectures, 
which will fix this. But this illustrates that:

* Either the Breaks: statement should be revised. Maybe it should target releases 
  older than a specific version for instance or could be removed.

* Or one should not just rebuild the package for a subset of the architectures to 
  avoid breaking multi-arch.


Note that libanjuta-3-0 and libanjuta-dev suffer from the same issue.
