gnetlist: segfault if text is attached to component

in contrast to the attached file, this works ok (note the different placements for the last curly brace):
v 20100214 2
C 40000 40000 0 0 0 title-A4.sym
C 43200 44900 1 0 0 resistor-2.sym
{
T 43600 45250 5 10 0 0 0 0 1
device=RESISTOR
T 43400 45200 5 10 1 1 0 0 1
refdes=R?
}
T 43500 44700 9 10 1 0 0 0 1

The verification performed on attached attributes when extracting name/value is insufficient : it is expected that any text objects attached to a symbol is an attribute. However as in your case, a text object that does not have a valid attribute string (the <name>=<value> format) can be found.

The patch below should fix that problem.

This Tracker item was closed automatically by the system. It was
previously set to a Pending status, and the original submitter
did not respond within 14 days (the time period specified by
the administrator of this Tracker).

Is there any way of doing this that doesn't involve an if-expression with side-effects?

(I've committed this patch anyway).
