Syntax errors are detected in generated GRUB config file

[arpanaut]

I receive this error after running 'update-grub' from a terminal and after a new kernel is installed from synaptic.
when I go to the advanced options for this particular install, the computer immediately reboots.
Also when viewing additional options from the grub menu of other installs there is an incredibly long list of lines for possible boot options.
This machine has 4 HDD with 7 different installations of Ubuntu & 1 Win XP,
1 Lucid
1 Natty
2 Precise
3 Quantal
The grub menus of the older installs have the spamed effect showing too.
will attach example.

There are 20+ additional lines below what is visible.
This is from a precise install grub screen after a 'update-grub'.
This was after grub-pc ver. 2.00 was installed on 2 Quantal installations.
