gEDA-user: vexing problem: m4:stdin:7: bad expression in eval

[Traylor Roger <traylor@xxxxxxxxxxxxxxxxxxxx>]

Guys,
  I have been adding symbols to a schematic I'm
  building and now the additon of a new symbol
  causes an error that I cannot figure out.

  Background:
    gEDA/gnetlist version 20061020, Ubuntu 7.04
    Four page schematic.  
    Have been making and adding symbols for weeks without problems.
    Everything working well through to complete layout in pcb.
    Built a new symbol today.
    Symbol checks fine with gsymcheck -vv.
    Did some system updates today in Ubuntu 7.04. Mostly
    safe stuff like openoffice, firefox; but some linux stuff.
    (Kicking myself for doing the updates now.)
  Symptoms:
   1. Whatever page I put this symbol on, gsch2pcb locks up
      for 2-3 minutes with the message:
           m4:stdin:7: bad expression in eval: /2
      then it says:
           m4: memory exhausted
      Then it finishes out things farily normally.
   2. When this behavior occurs, I see the following from gsch2pcb:
      R303: added new m4 element for footprint   0805 (value=4.7K)
      ----
      : added new m4 element for footprint    (value=)
      ----
      Note the last line.  No Refdes, no value.  Odd...
   3. Other new symbols I make do not seem to cause errors,
      but when added to the schematic page, do not show up as
      newly added parts with their refdes listed.  And... you 
      always see this line reappear:
      ----
      : added new m4 element for footprint    (value=)
      ----
   4. Same problems persist after reloading gEDA suite.

Any ideas?  I've been stumped for hours.

Thanks,

Roger Traylor
