nrpe plugins fail when pass arguments

[Joao Ferreira gmail]

Hello,

I have a strange issue with nrpe

- nrpe compiled with support for arguments
- option dont_blame_nrpe = 1

plugins fail if I pass arguments; tested with check_tcp, check_icmp and
check_load; none of them works if arguments come from the nagios
station; they all work if arguments are statically written in nrpe.cfg

I've tested the same command:
- 1st with all args typed directly in nrpe.cfg: works fine
- 2nd with args passed from the "client": fails.

bellow a log with details; the only difference between the 1st and the
second is that the 2nd receives args from the "client" nagios station

Thank you
Joao
