I don't think that's the case because 9 times out of 10 the page loads. 
If you hit refresh a few times you'll catch the error, then refresh and
it'll work again.

I have near-zero experience with putenv(), but my first impression on
looking at the code is that it looks like it will break if shell
metacharacters or anything other than low ascii is in the php vars.

Could there be stray newlines or some other characters in the values that
would cause breakage?
