#1  0x0000000000736d13 in fpm_status_handle_request () at /home/alp/build/php5-5.3.10/sapi/fpm/fpm/fpm_status.c:128

the patch looks good, but it is better assign this to fat, and ask for his 
reviewing :) thanks

I'm on it.

I've found this bug few days ago and I was waiting to finitsh something in the 
fpm_status code to fix this bug.

I'll fix this now but I won't use the patch as there's something cleaner to check 
the presence of some parameters in the query string.

i'll try to push this patch this morning.
