On a couple of occasions, I've had a similar problem that was the 
result of Apache having multiple processes running, and 1 of the 
running processes was failing while all the others were okay.

Try refreshing about 20 times and see if the problem comes and goes or 
if it only occurs on the first connection.

In any event, restarting Apache fixed the problem for me.
