[sword-devel] book arithmetic error in engine, Matthew -> Malachi

I could use a clue for what I'm seeing in the engine when changing books.
Xiphos' navbar provides arrow buttons for navigating up/down a single
book, plus the spinner which provides the same function. The code which
reacts to this is:
tmpkey = backend->get_valid_key(navbar.key->str);
vkey = tmpkey;
book = (direction)?(vkey.Book()+1):(vkey.Book()-1);
tmpkey = g_strdup_printf("%s 1:1",vkey.getBookName());
Pretty straightforward. When Xiphos is sitting on Matthew, hitting the
up button should result in a new selection of "Malachi 1:1" in the final
setting of tmpkey, but what we actually get in that case is "Zechariah
1:1". The engine has mis-analyzed where "one backward from Matthew" is.
I've looked at the usage of Book (that is, getBook and setBook) in
sword/src/keys/versekey.cpp, and I am a bit mystified by where this
mis-setting can occur.
