The description and fix sound exactly right.  I've encountered similar
problems with some of my "snd " resources under 6.0.7.  Worse,
sometimes the sounds just don't play; other times the Mac bombs with
an "unimplemented trap" error.

A solution for those who don't like to fool with ResEdit is to use
Sound Mover (I'm using version 1.61c) and simply copy all the sounds
from one suitcase into a new suitcase.  Sound Mover appears to
normalize "snd " resources that have garbage values in the fields in
question.  The newly copied sounds can then be played successfully
under either 6.0.7 or earlier systems.

This, of course, raises the question of why the code that plays "snd "
resources doesn't first do some sanity checking.  It's great that
Apple spent the time changing their bomb boxes to print semi-English
error messages; however, it would be better if they wrote code that
helped avoid those messages in the first place.
