Package: lintian-brush
Version: 0.112
Severity: normal
Tags: patch

Dear Maintainer,

The "lintian-brush" package uses Repository.get_revision_deltas from
python3-breezy.  This is not available in 3.1.0-8, but us available in 3.2.1-1.

The bug is only visible on a "stable" system using lintian-brush from
"unstable".


With lintian-brush 0.112 and python3-breezy 3.1.0-8 installed I get an error
after changes have been made, but before any git operation:

    $ lintian-brush                                                             
   
    Traceback (most recent call last):

line 157, in _changelog_stats
        get_deltas = branch.repository.get_revision_deltas
    AttributeError: 'LocalGitRepository' object has no attribute 
'get_revision_deltas'


With lintian-brush 0.112 and python3-breezy 3.2.1-1 installed, lintian-brush
runs as expected, and makes the world a little bit better again.
