Segfault on long memo fields

I have one table where the user has pasted some notes from another
application into a 'comments' field of type 'memo' and mdb-export segfaults
when it gets to these notes - they are quite long and contain tabs. 

I am not sure whether it's the length of the data or that it includes
non-ascii characters, but I just wondered if anyone had any ideas tracking
down the problem - I have had a look at the source code for mdb-export but I
don't know C very well so I'm not getting very far. I get the feeling it's a
buffer overflow or character (tab?) handling issue somewhere?

Any thoughts on where to look?

Thanks
