In general we want to use python variable names for plugin names. So really it should be either 'bzr_pqm' or 'pqm'.
I think there is a lot of precidence for using 'bzr-foo' for a plugin named 'foo'. as the launchpad project. And IIRC launchpad doesn't let you use underscores in project names. So we have a fundamental incompatibility between launchpad names and plugins that want to use valid python names.
However, since you only changed the project name to bzr-pqm, but left the installed path as 'pqm', the change seems fine.
