It seems dev-vcs/bzr-svn-1.2.2 is incompatible with subvertpy built against >=dev-vcs/subversion-1.7. At least that's the way https://bugs.launchpad.net/ubuntu/+source/bzr-svn/+bug/1187840 sounds to me. In at least one of my branches, "bzr info" yields the following backtrace: bzr: ERROR: exceptions.ImportError: cannot import name CommittedQueue Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/bzrlib/commands.py", line 920, in exception_to_return_code return the_callable(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/bzrlib/commands.py", line 1131, in run_bzr ret = run(*run_argv) File "/usr/lib64/python2.7/site-packages/bzrlib/commands.py", line 673, in run_argv_aliases return self.run(**all_cmd_args) File "/usr/lib64/python2.7/site-packages/bzrlib/commands.py", line 695, in run return self._operation.run_simple(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/bzrlib/cleanup.py", line 136, in run_simple self.cleanups, self.func, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/bzrlib/cleanup.py", line 166, in _do_with_cleanups result = func(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/bzrlib/commands.py", line 1148, in ignore_pipe result = func(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/bzrlib/builtins.py", line 1842, in run verbose=noise_level, outfile=self.outf) File "/usr/lib64/python2.7/site-packages/bzrlib/info.py", line 378, in show_bzrdir_info outfile) File "/usr/lib64/python2.7/site-packages/bzrlib/info.py", line 394, in show_component_info format = describe_format(control, repository, branch, working) File "/usr/lib64/python2.7/site-packages/bzrlib/info.py", line 499, in describe_format format = controldir.format_registry.make_bzrdir(key) File "/usr/lib64/python2.7/site-packages/bzrlib/controldir.py", line 1346, in make_bzrdir return self.get(key)() File "/usr/lib64/python2.7/site-packages/bzrlib/registry.py", line 177, in get return self._dict[self._get_key_or_default(key)].get_obj() File "/usr/lib64/python2.7/site-packages/bzrlib/registry.py", line 74, in get_obj self._obj = get_named_object(self._module_name, self._member_name) File "/usr/lib64/python2.7/site-packages/bzrlib/pyutils.py", line 51, in get_named_object obj = __import__(module_name, {}, {}, from_list) File "/usr/lib64/python2.7/site-packages/bzrlib/plugins/svn/workingtree.py", line 35, in <module> from subvertpy.wc import ( ImportError: cannot import name CommittedQueue bzr 2.5.1 on python 2.7.5 (Linux-3.9.7-gentoo-x86_64-AMD_Phenom-tm- _II_X4_945_Processor-with-gentoo-2.2) arguments: ['/usr/bin/bzr-python2.7', 'info'] plugins: bash_completion[2.5.1], bisect[1.1.0.pre.0], bzrtools[2.5.0], changelog_merge[2.5.1], cvsps_import[unknown], launchpad[2.5.1], netrc_credential_store[2.5.1], news_merge[2.5.1], po_merge[2.5.1], qbzr[0.23.0], rewrite[0.6.3dev], set_root_id[unknown], svn[1.2.2], weave_fmt[2.5.1] encoding: 'utf-8', fsenc: 'UTF-8', lang: 'de_DE.utf8' *** Bazaar has encountered an internal error. This probably indicates a bug in Bazaar. You can help us fix it by filing a bug report at https://bugs.launchpad.net/bzr/+filebug including this traceback and a description of the problem. This might end up as a mask on bzr-svn for the time being. Seems Ubuntu dropped the package for now, too. Let's see whether upstream will act on this; apparently there hasn't been any activity on bzr-svn in quite a while.
Comment from upstream: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=709223 Sadly speaking, I guess we need to remove it. I'm a regular user of it so I guess I need to go git-svn.
Ok, sad, masked for removal in one month (06 Sep 2013)
