Bug#705080: libpango1.0-0: version conflict between i386 package and "all" arch package renders both un-updateable

[Alex Vanderpol]

Package: libpango1.0-0
Severity: important

Dear Maintainer,

Unfortunately, the latest update to libpango1.0-0 did not end up fixing the
issue I was having previously, and creates a new problem on top of that as now
the "all" arch package and the i386 package are no longer equivalent versions
and therefore cannot be co-installed. As such, all of the new packages that the
"all" arch is supposed to be a transitional package for are also no longer at
matching versions in amd64 and i386, making it impossible to co-install them.

This is the output from Aptitude when trying to update libpango1.0-0 (for "all"
arch, on an amd64 system):

The following NEW packages will be installed:
  libpango-1.0-0{ab} libpango-1.0-0:i386{ab} libpangocairo-1.0-0{ab}

  libpangox-1.0-0:i386{a} libpangoxft-1.0-0{ab} libpangoxft-1.0-0:i386{ab}

The output from Aptitude is similar if I try to update libpango1.0-0:i386.

I don't understand why the i386 packages on my multiarch system aren't properly
recognizing the "all" arch transitional package as being installed and
insisting on trying to install the package from the i386 arch. I will have to
try to investigate this further and see if I can't figure out why this is not
working as it should be.
