This smells like the long standing ugly bug that was exposed by hyphens in 
footprint file names. IIRC, gedalib would interpret these names as M4 
code. This code path would fail silently but yield invalid PCB syntax. 
Depending on the exact circumstances, PCB would sometimes choke on the 
resulting file. Sometimes, it would work seemingly fine but fail later.

What version of geda and pcb do you use?
