Revisiting this, it turns out it hangs due to the .disk/info file
missing, not README.diskdefines as I previously thought:
A more suitable patch might be:

Title:
scripts/casper-bottom/41apt_cdrom is missing some sanity checking, can
cause hang on boot
Status in “casper” package in Ubuntu:
Confirmed
Bug description:
Distribution Release: 12.04 Precise
Casper: 1.296
in scripts/casper-bottom/41apt_cdrom, if an apt repository is not configured in the root of the LiveCD, the script hangs the boot process waiting for input with the message:
"Please provide a name for this Disc, such as 'Debian 5.0.3 Disk 1"
Some sort of checking is needed here to see if the conditions required for the apt-cdrom repository are fulfilled, and to fail silently if they are not - I've attached a possible patch:
* if /README.diskdefines does not exist in the root of the CDROM, exit with no error
having said that I'm not certain of the role of the
README.diskdefines file, so it may not be the best choice for
checking.
