Fix a SIGSEGV

This is pretty awful, but will let me wire up items more easily without
needing to do the big refactor into independent menu handlers

-The "trailer trailer", for want of a better term, seems to be organised as:

+suggested above:
+

+| 1660   | 1?   | Orientation? Could also be `0x680`... |
+| 1661   | 31   | ??? |
+
+There's still a lot of bytes to dig through, but this allows me to load the
+character names from Chapter01 correctly, with the exception of record 57 which
+just contains `\x02` and is then null-terminated all the way through - but maybe
+that's just a data thing.
+
+How about their types? `HasAction.dat` lists numbers for character types, and
+those show up immediately before the name. Going from the character type to the
+animation group is not yet fully deciphered - squad leaders mess up a direct
+correlation - but a fixed offset table allows me to draw the characters \o/.
+
+Putting 8 characters onto a map and orienting them in the compass points, we see
+numbers ranging from 0 to 7 at 0x67c and 0x680. Assuming this is the scheme
+used, north is value 1, northeast value 2, and northwest value 0.
+
+Given two characters of the same type, just in different locations, differing
+values are seen at:
+
+* `0x103 - 0x10c` (hodgepodge)
+* `0x178 - 0x1be` (hodgepodge)
+* `0x2fc` (0, 1) - squad number?
+
+
+I can easily correlate certain bytes in the first range to various character
+attributes. A few remain unset.
+
+In Chapter01, picking a random character (Gorgon) and looking at his squadmates,
+they are all in the same squad, and no other characters are in that squad, so it
+looks pretty diagnostic to me. There's nothing in the UI to indicate the squad,
+though.
+
+Now let's look for position. In my 2-character map, they're at 65,50 and 70,55.
+Within a character, I see those numbers repeated twice - around `0x1b{9,a}` and
+`0x1b{d,e}`. This may be some kind of multiple-squares-taken-up thing.
+
+Adding a (tall) Lord of Change to the map gave me `02 36 45 00 02 37 45`, which
+doesn't quite match what my eyes are telling me for Z,Y,X. In addition, the data
+immediately after this offset changed into a large number of coordinate-like
+sets of values - far too many for it to actually be a bounding box. However, the
+first one remains good as a position specifier.
+
+Down in `0x679` (Chaos Sorcerer) or `0x68D` (Lord of Change), the map coords for
+the *other* character appears, which is downright odd. For now, just use the
+first-indexed value.
+
+Thingies next: these aren't decoded at all yet, and the sizes seem to be
+variable.
