Theme activation fails if partner has no logo

[timlinux]

I tried to make a partner with no logo (dumb I know :-P ) and then associate it with my theme. When I pressed activate in admin I got this error:

Traceback (most recent call last): File "/usr/src/geonode/geonode/client/admin_actions.py",

ValueError: The 'logo' attribute has no file associated with it.

Removing the partner from the theme, saving it and then activating worked successfully.
