http://bugs.koha.org/cgi-bin/bugzilla/show_bug.cgi?id=1389 but it's
not the same problem.

Thanks.

No, it isn't.  $server comes from the results of the query
  select * from z3950servers where id=?
and on my server, z3950servers includes:
+------------------+------+---------+
| host             | port | name    |
+------------------+------+---------+
| z3950.loc.gov    | 7090 | LOC     |
+------------------+------+---------+
while on your server, I'll bet that host was Library of Congress,
while name was z3950.loc.gov - the fields were backwards.

Not sure how that would have happened.  I guess "Z39.50 Server" on
http://sitename:8080/cgi-bin/koha/admin/z3950servers.pl
is a bit confusing and badly placed in the form.  I've put the
following patch in for the next version:
