#7184 MOHAWK: Riven crash on Bookmaking Island

[Bruce]

Current Daily Build: 1.9.0git4334-g7234f07 (16 Aug 2016)

Game Version: English, 5-CD (contains v1.02 patch files)
Platform: Intel Mac (OS X 10.6.8)

Bug details:

The game crashes if I try to turn back after reaching the frog trap at the end of the tunnel (on Bookmaking Island)… I can go forward, but not back.

There are 2 other instances over the next 3 consecutive scenes (including entering the air duct) where the same crash can occur:
1. Attempting to turn back while viewing a close up of the fan (spinning or not).
2. Attempting to move forward after exiting the duct at the tunnel end (matches turning back from the frog trap).

OS X error reports:

• Console message:
  scummvm[xxx] ../../src-master/src/common/array.h:169: failed assertion `idx < _size'
