How to properly deal with RefSeq pseudogenes without transcript?

[soi]

In the new refseq human and mouse genomes, there are many pseudogenes annotated with exons but no transcript (makes sense I guess).
The types.py lists pseudogenes as valid super locuses, so how should we deal with that? I added some code that basically throws the exons away, leaving empty genes that are also discarded later, resulting in many error messages.
