I've look at the program field and it's empty.
It seems that syslog-ng try to find the attribute program before ":" and my
logs starts with this ":". Printing the progam attribute in my log show me
that this attribute is really empty.
So I'd like to make a filter using a matcher for the ":" of the message and
another matcher on the empty program attribute.
