Game crashes at Squidstone arc after freeing bonzai

[h3rmit-git]

The game crashes in a weird way after knocking off the rocks that are trapping the bonzai at Squidstone arc.

After the bonzai slips down, the hero starts sliding instead of walking. After a few attempts to walk, the game crashes.

I verified the version, it's 1.1a.

EDIT:
I tested it some more, and it turns out that simply throwing a rock at the bonzai leaves the hero in a "sliding" state. While in that state, attempting to walk causes a crash:

Throwing another rock at any other target restores the hero's state, and you can walk again without a crash.

The problem is that once the bonzai is freed, the hero is in the "sliding" state, but the game prevents us from throwing any more rocks, displaying a message "You missed." Attempting to walk or pick up the bonzai in that state leads to a crash.

Update:

I published a quick fix for it here, until it's included in the next release of QFG4-Enhanced:
