Right, I've just made a new directory, put in the two source files, run
gsc2pcb test2.prj in it and created the three output files. The .net
has the trailing continuation character.

So it's either the environment here or a library issue, as I assume
gsch2pcb uses the system gafrc file. Many of the components are custom,
so it's entirely possible one or more is broken. That's still worth
chasing, I think, as I'm not the only one building components, and I'm
not aware of anything I've done wrong. I'm still hoping, when I get the
time, to upload them to geda-symbols, so I'll need to identify the
faulty one(s). The problem there is that any change at all I have so
far made to the schematic has removed the problem, so it's probably
a combination of a faulty component definition and very bad luck in the
order of adding and removing things.

I think perhaps that this shouldn't be pursued any further. It's
obviously a one-in-a-million chance that I have found this, even on my
system, and it's probably one of my components at fault, so with luck
nobody else will ever see it. Unfortunately I am extremely pushed for
time at the moment, and if I can identify the problem at all, it will
take a couple of extremely tedious days. Obviously if I do learn
anything I'll report it.

Thank you for your time and effort.
Joe

Title:
  PCB shuts down after opening file with empty Connect("")

Status in GPL Electronic Design Automation tools:
  Incomplete
Status in PCB: Printed Circuit Board CAD package:
  New

Bug description:
  After editing a schematic in gschem and using gsch2pcb to create a new netlist, a space was left at the end of a net after a line continuation character. This led to an empty connect statement in the net after import to the PCB file [Connect("")] and after this PCB would immediately shut down on opening the file without leaving any error record, even when started from a command line. The PCB file is OK after removing the connect statement.
  The net with the space was the last entry in the netlist file, and before the schematic was edited, that entry had run onto the next line after a continuation character but was now shorter.
