It's not an error with fglrx. Your GPU (RadeonHD 3100) is no longer supported by recent versions of fglrx: http://www.phoronix.com/scan.php?page=article&item=amd_catalyst_legacy2&num=1
The "legacy" version of Catalyst 12-6 supports your card, but it only supports kernel <= 3.4 & Xserver <= 1.12 and, therefore, is not compatible with Ubuntu Quantal/12.10
Basically, either Ubuntu offered to install fglrx for you (and the bug should be reassigned to ubuntu-drivers-common package because that shouldn't happen) or you installed fglrx on your own accord (and the bug should be marked Invalid).
