I don't know if this will help or not, but when I uninstalled gnome 3.8 and took the ppa:gnome3-team/gnome3 off of my sources list, it completely stopped crashing.
Before I uninstalled gnome 3.8, I had tried reinstalling and purging the software center through both apt-get and synaptic.
Once I downgraded back to the original gnome version that came with Ubuntu 13.04, it started working perfectly.
I hope this helps and I hope I am posting in the correct place.
