I traced this to the bzr_log method in the plugin, and patching that seems to fix it. The plugin just needs to parse the input little bit differently.

+ Subject: [PATCH] Fix bzr plugin to work with bzr 2.0.
+
+ The output of "bzr log" seems to have changed a bit, so we change the
+ parsing accordingly. This has not been tested with earlier versions of
+ bzr.
+
+ Several problems seemed to occur, all in the bzr_log subroutine:
+
+ 1. The @infos list would contain an empty hash, which would confuse the
+ rest of the program.
+ 2. This was because bzr_log would push an empty anonymous hash to the
+ list whenever it thought a new record would start.
+ 3. However, a new record marker (now?) also happens at th end of bzr log
+ output.
+ 4. Now we collect the record to a hash that gets pushed to the list only
+ if it is not empty.
+ 5. Also, sometimes bzr log outputs "revno: 1234 [merge]", so we catch only
+ the revision number.
+ 6. Finally, there may be non-headers at the of the output, so we ignore
+ those.
