Comment (by dwatteau):

 @raziel- Thanks for your test!

 I don't think this is related to the guy who arrives on a camel's back.
 Because he only appears near the end of the game, but I can also trigger
 this issue in Act 2 or once he's gone. Similar lock-ups happen in some
 other parts of the game, too. With the camels it just appears to be a bit
 more likely to happen, for some reason...

 I wonder if this could be related to the camels triggering a very frequent
 noise with their mouths; i.e. when you leave the scene, you're switching
 from a background music to another one, but with some timing both the
 music and SFX will be triggered at the same time, leading to this lock-up
 or something like that. Just a very wild guess while putting some logs
 around setMusicSceneDetails() though... I may be completely wrong.

 https://www.lspace.org/games/discworld/faq.html#part3.5 mentions that
 there originally were some random issues around the camels, but I think
 our engine is based on the later interpreter which fixed this, and lock-
 ups aren't mentionned there.
