[Koha] Z39.50 General query term problem

[Mike Dalgity]

I'm having a problem when searching a certain Z39.50 server for more general
search terms suchas Authors and Titles.  I have no problem with the same
query with AMICUS and LoC and I also do not have a problem with a more
specific searchs such as an ISBN.  One general search term I used is
"Tolkien, J. R. R." in the author field.  The server configuration
information is here http://library.dts.edu/Pages/Help/Tech/z39.50.shtml


I get a 500 Internal Server Error in the browser and the following in the
error log:
something went wrong: No error at

Any ideas about what's wrong or where to start troubleshooting?
