RHEV-Hypervisor6-6.5-20140112 Installation error regarding keyboard

When attempting to install the RHEV Hypervisor 6.5 (20140112) from media, I receive the following error immediately after selecting my keyboard as 'US English'.

An error appeared in the UI: KeyError('label.details',)
Press ENTER to logout ...

or enter 's' to drop to shell

I have attempted the install using standard UI and using basic UI, the error occurs at the same spot for both.
Media checks complete 100% and have used the media elsewhere to install.

A point to note is that the keyboard is PS2 (HP branded), not USB. Will test with USB in future but unfortunately don't have one on hand at the minute.
