Another example

$ bzr push
Using saved push location: bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.1.39-oqgraph/
Unable to obtain lock lp-46129552:///~maria-captains/maria/5.1.39-oqgraph/.bzr/branch/lock

Will continue to try until 01:25:56, unless you press Ctrl-C
If you're sure that it's not being modified, use bzr break-lock lp-46129552:///~maria-captains/maria/5.1.39-oqgraph/.bzr/branch/lock
bzr: ERROR: Could not acquire lock "(remote lock)":

(trying with the suggested URL)
$ bzr break-lock lp-46129552:///~maria-captains/maria/5.1.39-oqgraph/.bzr/branch/lock
bzr: ERROR: Unsupported protocol for url "lp-46129552:///~maria-captains/maria/5.1.39-oqgraph/.bzr/branch/lock"

(this works, using the url from bzr info)
$ bzr break-lock bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.1.39-oqgraph/
Break lock bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.1.39-oqgraph/.bzr/branch/lock

In a nutshell, the url shown is wrong/invalid/unusable.
Solution: change it ;-)
