I'm having the same issue.
Ubuntu GNOME 13.04 64 bit. Gnome 3 PPA enabled. Fully updated, 3.8.0-26 kernel. Fully updated as of July 7th 2013. I haven't been able to open the software center for quite a while now, but I've just ignored it, however it's wearing on me now.
Some things I tried:
http://paste.ubuntu.com/5852888/ http://paste.ubuntu.com/5852894/ http://paste.ubuntu.com/5852904/
All did nothing.
