[Pkg-bazaar-maint] Bug#637607: bzr-dbus: crashes if ‘gobject’ module not available, but package dependencies do not require it

[Ben Finney]

Package: bzr-dbus
Version: 0.1~bzr50-1
Severity: important

The dependencies for ‘bzr-dbus’ are:

=====
Depends: bzr (>= 1.0), python-dbus, python2.6 | python2.7, python (>= 2.6.6-7~), python (< 2.8)
Suggests: bzr-gtk, zeitgeist
=====

This system therefore has no ‘gobject’ module for Python:

=====
>>> import gobject
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named gobject
=====

But the ‘bzr-dbus’ code crashes as though it depends on that module:

The package should either be changed not to depend on the ‘gobject’
module, or the package dependencies should declare that dependency.
