jQuery Grid Plugin - jqGrid

I have an urgent issue. I am populating my brid like below. The first time my page loads, it builds the grid fine. If I click "next page" to go to page 2, it works fine. If I click next page again (only 3 pages total), it actually pulls the data and you can see it but the "Loading..." image stays up and I can see I have a Javascript error, it says "'undefined' is null or not an object'" and none of the buttons on the grid work anymore.

I tried using Visual Studio to debug the JS error and it is in the jqGrid's Javascript (but its minified) and it's something on the line , maybe 36 and it looks like

n=P[c];C=n[G];

Here, apparently n is undefined after the assignment (for some reason when this happens, "c" is equal to 3). This part may be wrong, it's just what I gathered trying to debug it.

This WORKS in Firefox 3.0.17.
