just a comment but before upgrading to the 13.04 beta from 12.10 .. I used clonezilla to copy my 12.10 to a 2nd HD. When the problem happened to the 13.04 system I figured while troubleshooting I'd just use the 12.10 disk when needed. It worked okay until a sudo apt-get update && sudo apt-get upgrade on that disk updated something also. Now... both the 12.10 and the 13.04 disks (separate HDs booted via grub)... are having this same problem. Only posting this because I thought there might have been a common update to both 13.04 and 12.10 that could give a clue to root cause.
