The only reason for this strange behaviour that I can think of is that 
XFCE4 and GNUstep disagree on the handling of focus events. It would 
help to get a full list of the events that show up during that problem. 
It is easy to get this events displayed on the prompt when you start up 
the GNUstep application with the additional argument --GNU-Debug=NSEvent
This will result in a lot of output, please only forward the ones that 
happen just around the minimalization of the other application.
