Well, the consensus answer to my query on the cause of unexpected error 8454
is that it's due to an internally corrupted stack, and the best way to recover
from it is to use a stack called RecoverStack. A stack from sumex called
Hypermerge may also be useful in recovering incorrupt cards.

As to avoiding the problem in the first place, the best way is to keep regular
backups. There seems to be no correlation between stack size, hypercard
version, etc.
