Hello,

I'm working on a moderately large design, and for some time, I see two
strange things happening.

The first occurs when importing a gschem schematic in PCB; I get the
exact same error message as reported here:
http://comments.gmane.org/gmane.comp.cad.geda.user/39657

Apparently, my schematic contains off-page connectors -- the trouble is
that I didn't consciously define any such, neither can I find any 'loose
ends' or other irregularities among the 50 or so named nets in the
schematic.
Apparently, this message is basically harmless, but I still wonder is
there's an easy way to identify these items?

The second mystery has to do with the bom generated by PCB -- it says
that there are 14 elements with unknown refdes, unknown footprint, and
unknown values:

14,"(unknown)","(unknown)",(unknown) (unknown) (unknown) (unknown)
(unknown) (unknown) (unknown) (unknown) (unknown) (unknown) (unknown)
(unknown) (unknown) (unknown)

Could this be related to the first problem? When I look at the .pcb file
with a text editor, I can't find any reference to these 14 elements, and
opening the gschem file with gattrib doesn't show anything out of the
ordinary either.

AFAICT, every 'real' component is properly accounted for, but I don't
like it when things happen that I don't understand -- especially when
they might lead to real errors.

Thanks in advance,

Best regards,

Richard Rasker
