Having multiple netnames should not be a problem and work "sometimes". 
Actually I worked arround that problem while
renaming one net to 4th name( PLUS_). The warning is still there, but 
all nets are now connected. The job for the software is still simple:
collect all connections for all nets which are interconnected in one 
list with one of the net names (simply the first name :-). Thats all and 
this should not result in redesigning symbols. And yes, I have own 
symbols which use net attributes to connect default nets to 
sub-schematics. As I think, there is simply a bug inside the netlister?!

I use AT90S8515_DIP.sym which is  really a bit terrible, because it is 
not possible to use another footprint like smd or plcc or something 
else. This is the old discussion of using numbers, meaing a pin 
sequence, not logical pins. If using logical pins, maybe with names like 
PD0..PD7 and so on, we would be able to use all footprints with one 
symbol.  I did this work for transostors for me, because I would not 
change my circuit only while having an other package. But this is 
another topic :-)

 Klaus
