The problem narrowed down:

	The Dialog::Accept crashes when a containing stringeditor contains
a string pattern "abcdef " (note the space after f) and any additional
characters after the space.  If I have a space replacing any of "abcdef" chars
above, the bus error does not occur.

	I patted on my back (with agony) for selecting "spring tension" as my 
test string.  I am truing to isolate the problem to StringEditor, if at all
possible.
