Empty IP when forwardfor enabled

I've setup two frontends balanced with Haproxy (excellent software) in another server:

       Load balancer
              / \
            /    \
           /      \

Frontend 1 Frontend 2

I have enabled "option forwardfor". I have set LogFormat in Apache configuration file as follows:

LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

but many times the IP field appears empty. I've read on this mailling list that it has something to do with KeepAliveTimeout on Apache. I rised up it from 6 to 15, but no luck.

How could I fix this?
