s/tight/right/, it was a typo. The idea is to see whether gsch2pcb makes 
something strange to your pcb file or PCB does something strange to it 
after loading the nets.

I have no idea what the GUI wrapper does, but it should have access to the 
command interface of PCB so in theory it could rename components or pins. 
However, if you've seen all pin number correctly after a 'd' and the 
refdes labels are correct too and the netlist looks ok too, then I still 
suspect it's some local PCB bug. This, however, contradicts with the fact 
you see the same problem with different PCB versions.

Maybe looking at the .pcb files at different stage would reveal something 
I missed.

For small projects I usually go without the .prj file. As long as the name 
of the pcb and sch files are the same (without the suffixes of course), 
the defaults are usually good enough to just run "gsch2pcb foo.sch". I did 
the test on your files that way. Maybe you should try that too, although a 
straightforward prj file wouldn't mess up the netlist.
