problems with scaffold generated list

There appears to be a problem with LIST generated from scaffold.
I just dumped the contents of a table that stores Service Pack
Descriptions...

ID Title
1 Any
2 SP0
3 SP1
4 SP2
5 SP3
6 SP4
7 SP5
8 SP6
9 SP7
10 SP8
11 SP9
12 SP10

Notice there are 12 entries.
From a rails generated scaffold with no modification, I get the
following for the 1st page of LIST...
Listing service_packs
Title
Any Show Edit Destroy
SP0 Show Edit Destroy
SP1 Show Edit Destroy
SP2 Show Edit Destroy
SP3 Show Edit Destroy
SP4 Show Edit Destroy
SP5 Show Edit Destroy
SP6 Show Edit Destroy
SP7 Show Edit Destroy
SP8 Show Edit Destroy
Next page
New service_pack

So good so far, but them pressing next page, I get...

Listing service_packs
Title
Any Show Edit Destroy
SP0 Show Edit Destroy
Previous page
New service_pack

Notice it just shows the fist two entries, instead of 9 - 12 like it
should...

Does anyone know what is happening here and how I can correct it?
