[rsyslog] properties not getting filled in correctly

[david at lang.hm]

I'm running into problems trying to do filtering. it looks as if the log 
parsing is not properly filling in the properties.

what I've run into so far

when I use the property 'programname' the content that I see is what I 
would expect in 'hostname'

when I use the property 'hostname' the content that I see is what I would 
expect in 'fromhost'

I haven't checked all the other properties, but my guess is that somehow 
rsyslog is off-by-one in filling them in.
