Problem with the node_age filter

I am using PHP 4.4.7. I don't know if this is related or not, but basically there's a problem with the range() function when trying to use the form for looking at the filter node age form:

Wrong parameter count for range() in xxx/sites/all/modules/spam/filters/node_age/node_age.module on line 111.

which then leads to empty dropdown lists for selecting the age ranges.

Writing this made me take a closer look, and actually, this is something already taken care of in most of the module with the 'spam_range' function. It's just not being called in the above. Not exactly sure how to submit a patch though, and am too tired right now to figure that out, sorry!
