Nginx Substitutions Filter problem

[Martronic SA]

Hello,

We are using the "Substitutions Filter module"
to replace html content in our pages.

Our configuration is :

location /{
subs_filter_types text/html text/xml;
subs_filter 'http://bale.hopla.net/bons-plans' 
'http://bons-plans.hopla.net';
subs_filter 'id="portal-logo" href="http://bale.hopla.net"' 
'id="portal-logo" href="http://www.hopla.net"';
}

The first substitution is working, but the second not.
Are we missing something? Is the "space" supported in substitution module?

Thank you for your help!
