Thanks for taking the time to report this bug, Peter.
Between 12.04 and 12.10, we had to start mounting encrypted home with the nosuid mount option to address CVE-2012-3409. I've verified that this is the reason why you can no longer use capabilities as you've described in the bug description.
I would suggest that you move the binary outside of your encrypted home directory so that you can still use capabilities. Sorry for the inconvenience.
