Comment 12 for bug 733136

As jam notes in https://code.launchpad.net/~mbp/bzr/733136-lock_url/+merge/55682 this probably means qbzr is doing something strange, like perhaps trying to update the config from one process while another one holds it open. The fix in bzr should make the error more obvious.

For people still hitting this, looking at the 'info' files inside the lock, and patching the process id in there to their command lines will help.
