I reckon you've got a bad pointer or two in the data somewhere.

The Ommis data transfer format keeps the internal Omnis data structure

lists etc. The downside is that it would keep bad data intact too.

So I would suggest export in tab delimited and import to a new  
datafile ( assuming you have no binary data fields to preserve in
