Software Center hangs on loading

[Rachael Ouwejan]

Can't get Software Center 5.2.6 to load correctly in 12.04

When trying to run from terminal got the following:

2012-12-12 08:25:28,311 - softwarecenter.fixme - WARNING - logs to the root logger: '('/usr/lib/python2.7/dist-packages/dbus/proxies.py', 410, '_introspect_error_handler')'

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

then it just hung until I killed it.

Have tried uninstalling, reinstalling, deleting cache, nothing has helped. debug software center hung, doing a unity reset resulted in some alarming looking (compiz?) errors I'll be submitting as a separate bug report :-)
