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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1163886 Title: software-center crashed with signal 5 with WebKit 2.0+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1163886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
