The message can be triggered by two different kinds of error:
1. A logic error in the BEAM runtime system causing it to access
   data using type-incorrect accessors.
2. Corrupt data that no longer matches the runtime system's
   expectations.

I don't know enough about mnesia to comment on whether it
could be the culprit here.
