I was testing the 20120605.2 i386 QQ image and ubiquity crashed before making any selections. Apport showed duplicate bug 1008818 as the culprit. I'm clueless regarding what other info might be helpful, but the 20120604.2 iso worked OK.

Oddly I just decided to see if I could reproduce that installer crash, same iso, same identical procedure and hardware, and things seemed to go just fine. It's installing as I type this.

I encountered this bug when I quit the installer during in installation of the quantal-desktop-i386.iso in VirtualBox on an Ubuntu 12.04 host. As also indicated in comment #7 also to me it was indicated that bug #1008818 was the issue.

Note 1: The reason to quit the installer was the fact that it indicated I was not connected to the internet. However, when opening Firefox it turned out I was connected.
Note 2: The issue did not appear again when restarting the installer, so maybe quiting it was the cause?
