Not necessarily, I'd rather guess at a bug in the indexing mechanism
that has been solved by now.

Some possible solutions:
* upgrade your Elephant
* rebuild your indices
* wrap your get-instances stuff in a function that removes
the NIL entries

No, that won't help. :)

FYI you can prevent deadlocks from appearing.

I don't think so.

I think there was an easy way but I can't remember it right now...
