I've just updated 20+ packages locally in a project's requirements file,
one of which has caused:

}}}
This model isn't defined in the project's own models so in this particular
case it must be django-browserid now clashing with one of the packages
that was updated.
Rather than having to bisect, it would be much more helpful if this
exception gave more details about the already-registered model, so I know
which package/app is clashing with the later app's attempts to re-register
it.
