Neil,
i've checked the additional information you requested:

1.bzr version is 2.3.4 on both locations
2. bzr info -v gives the following in local branch:

Shared repository with trees (format: 2a)
Location:
  shared repository: .

Format:
       control: Meta directory format 1
    repository: Repository format 2a - rich roots, group compression and chk inv
entories

Create working tree for new branches inside the repository.

Repository:
        38 revisions

and for network location :

Shared repository with trees (format: 2a)
Location:
  shared repository: .

Format:
       control: Meta directory format 1
    repository: Repository format 2a - rich roots, group compression and chk inv

3. also i send you , by email , my workflow that created the setup.

I need the full output from "bzr info -v", especially the sections title "Location" and "Related branches". I need to know how the relevant branches are related to each other so that I can test this. Alternatively, you could provide a reproduction recipe with dummy branches instead of showing your live setup.

i solved the problem.
the fact that the remote branch and local branch were bound , cause the lock problem.
i just did unbind and all is working fine.
thanks for your help

It seems like we could use a better error message in this case.
