[Bug 825689] [NEW] libqt4-dbus: contains an executable in /usr/bin, breaks multiarch, Policy 8.2

[Steve Langasek]

Public bug reported:

The libqt4-dbus package ships /usr/bin/qdbus, an executable that links
against libqt4-dbus but does not appear to be used by the library.  This
contradicts Debian/Ubuntu policy 8.2:

     If your package contains files whose names do not change with each
     change in the library shared object version, you must not put them in
     the shared library package.  Otherwise, several versions of the shared
     library cannot be installed at the same time without filename clashes,
     making upgrades and transitions unnecessarily difficult.

     [...]

     Run-time support programs that use the shared library but are not
     required for the library to function or files used by the shared
     library that can be used by any version of the shared library package
     should instead be put in a separate package.  This package might
     typically be named `<libraryname>-tools'; note the absence of the
     <soversion> in the package name.

This also breaks multiarch, since /usr/bin/qdbus has to be a file of one
architecture or another, preventing installation of multiple copies of
libqt4-dbus.

This is the only program in any of the qt4 library packages, and I think
it was put there by mistake.  Debian bug #391726 mentions that qdbus is
a "nice to have", and the other tools that were packaged at the same
time were put in libqt4-dev instead.  I think the correct course of
action here is to move the file to either libqt4-dev or qt4-dev-tools.

However, I'm sufficiently wary of breaking something here that I
hesitate to just upload the fix - so I'm raising a bug instead.
