10.04 install fails at bootsplash

[Robert Spanjaard]

On my machine, which had no problems installing any of the previous Ubuntu 
versions, the 10.04 live CD (on USB stick) fails to get past the 
bootsplash (with the red/white alternating dots). When I press escape to 
see why there's no activity (except for the dots which do keep changing), 
I get the following error messages:

(process:376): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
                                                                               stdin: error 0
stdin: error 0
stdin: error 0
stdin: error 0
stdin: error 0

The stdin-error is added five times everytime I switch between the
console and the splashscreen.

Personally, I doubt if the error displayed is actually responsible for
the failed installation, but this is all the information I can get.
All the Ctrl-Alt-Fx consoles are blank.
Does anybody know what (else) might be going wrong?
