Yup.

Uh, this is not *directly* the problem.

Actually, it's the other way round: a fax page is REQUIRED to be 1728
pixels wide.  Always.  (Unless you negotiate a different width).

Ghostscript, when fed a "setpagedevice" command for a different page width
than the default, will happily create pages with a different line width,
and thus make G3 files that cannot be sent by fax.  (Actually, this is 
not a bug in Ghostscript, because you might need this for A3 faxes.  I
consider this a bug in the postscript generation program, it just should
Not Do That, that is, send setpagedevice commands).
