@zeev: That vaguely sounds like a semi-jailbroken device. Make sure you don't have any piece old jailbreak left half-installed on the device.

Remove them, reboot the device, and try again.

EDIT: I'm assuming that by 'two different jailbreaks' you meant the release and the snapshot, which actually doesn't really make a difference in this case. That said, I don't recognise one of the filename you mentioned, so do make sure you got your files from here...
