[Bug 803362] [NEW] partial upgrade to oneiric (to keep bzr-svn installed) bails with bzr bd -S

[Steve Langasek]

Public bug reported:

Doing a partial upgrade to oneiric (because bzr-svn is not yet uploaded
for the latest bzr), trying to use bzr-builddeb gives errors:

$ bzr bd -S
bzr: WARNING: bzrlib version doesn't match the bzr program.
This may indicate an installation problem.
bzrlib from ['/usr/lib/python2.7/dist-packages/bzrlib'] is version (2, 4, 0, 'beta', 4)

bzr: ERROR: The API for "<module 'bzrlib' from '/usr/lib/python2.7/dist-packages/bzrlib/__init__.pyc'>" is not compatible with "(2, 3, 0)". It supports versions "(2, 4, 0)" to "(2, 4, 0)".

If I remove bzr-svn, the problem goes away.  If I upgrade bzr (which
removes bzr-svn anyway), the problem also goes away.

The package dependencies should prevent the system from getting into a
state where there are incompatible bits installed together like this.
