Case-insensitive collation on SQL 2000 and case-sensitive on SQL 2005?

Somehow, the only way I could see that this sequence could lead to
this error is that either the DELETE is incompletes with the incoming
data, or the incoming data itself has duplicates. I've seen many weird
bugs, but that DELETE would not have completed when the next statement
runs sounds a little fantastic to me.

But I've been wrong before.
