I simply set LC_ALL=pl_PL, global for system... Now I see how BAD idea it
is, especially when it comes to LC_NUMERIC ;)

The patch caused Smokeping to die at the start with "Resetting LC_NUMERIC
failed - try removing LC_ALL from the environment" message.
I have launched smokeping with: LC_ALL=C /etc/init.d/smokeping start - and
it worked! Finally I can test real response to http requests :)

Thanks for help!
