software-center crashed with signal 5 in _XReadEvents()

Software center seems to crash on the first launch after install.

I hit this on the saucy rc image from 20131016
The install I had done was amd64 desktop on virtualbox with free software only, no network connection.
Once booted after installing, I attached the network, brought up a terminal and ran apt-get update. Everything looked fine, so I tried running software center and hit this crash.

Running a second time, software center seems to come up ok though.
