Summary: Crash after exiting right side of Skate-o-Rama during chase

Initial Comment:
When being chased by Sequel Police in Space Quest X, I enter the Skate-O-Rama from the left, go right, up, left, back down, right again, and attempt to exit on the right steps.  As soon as I exit the screen, Roger crumbles from the "zap" animation, but he hasn't actually been shot.  If I click somewhere, either the game crashes immediately, or an eletrocuted skeleton floats for a second and then it crashes.  The ScummVM console prints the following:

ERROR: lookupSelector(): Attept to send to non-object or invalid script.  Address was 0000:0000!

stderr prints no errors or warnings; only warnings from FluidSynth are printed.  Attached is a ScummVM saved game right before the crash.  I've tried to reproduce with the original interpreter, but I can't even get that far: the SP shoot me as soon as I enter the skating rink.  :/
