I tried doing:

    bzr qlog . :parent :push :submit :bound

in a shared repository, and got:

    bzr: ERROR: Not a branch: "/home/users/russel/Repositories/Bazaar/Branches/Gant/.bzr/branch/"

If I do:

    bzr qlog .

in the same directory it works fine.

I tried cd into a branch and:

    bzr qlog . :parent :push :submit :bound

but that gives me:

    bzr: ERROR: No submit location assigned.

the problem here is the :submit and :bound which are not set on the branch.  Restricting to:

    bzr qlog . :parent :push

This started to show something but then crashed with what looks like a bzr-svn issue:

Upgrade to Subversion 1.5 or higher for faster retrieving of revision properties.
