Subject: sword key init bug tripped by refdoc's farsi "TPV" module

Peter von Kaehne ("refdoc") has produced a Farsi Bible module, "TPV",
with which I am experimenting in latest GnomeSword.  Mostly, things are
fine, but the module is inducing a core dump way down in Sword key
initialization, only when bringing up Rev 1.  Jude and Rev 2 are both
fine, indeed any other chapter seems fine.  Stack trace begins:

Program received signal SIGSEGV, Segmentation fault.

getZeroContent() is a function to obtain "0:0" content, that is, book
(and chapter, "n:0") headers.  This function operates just fine in any
other module I have on hand which has such headers, e.g. KJV and DM's
beta NASB.

The code in getZeroContent() begins
	mod->setKey(imodule.getKey());
	VerseKey *key = (VerseKey *)(SWKey *)*mod;
	int chapter = key->Chapter();
	char oldAutoNorm = key->AutoNormalize();
	key->AutoNormalize(0);

I wonder if someone familiar with key init issues could pick up this
module and trace through its use in Rev 1 to find why it has a problem
there and only there.  It can be found at ftp.kleinpaste.org in
/pub/sword; this is a Sword-ready repository, so your module manager can
pick it up the easy way, or else just go in via ftp and get the *.zip
the hard way from the "zip" subdir.

I have to say, seeing this module displayed on my screen makes me wish I
could read Farsi.  Good job, Peter.
