'bzr help branches' failed: bzr crashed with AttributeError in help(): 'Option' object has no attribute 'get_help_topic'

[Colin D Bennett]

Running Ubuntu Precise pre-release. Running 'bzr branches' in my repository with many branches doesn't show anything, so I tried 'bzr help branches', which crashes with this stack trace.

Package versions:
bzr 2.5.0-2ubuntu1
bzrtools 2.5-1

bzr: ERROR: exceptions.AttributeError: 'Option' object has no attribute 'get_help_topic'

I see that bzrtools decided to rename the “branches” command to “list-branches” [see below]

The list-branches command works fine. The 'branches' command needs to be fixed either in bzr or in bzrtools. Is “branches” some new core command related to colocated branches??? Is that why bzrtools renamed to list-branches?

bzrtools change that renamed 'branches' command:

  Rename 'branches' to list-branches, keep 'branches' as alias if not built in.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm also seeing this with 'bzr help tags'
