I think this might be the same error I had (See Ticket #230, fixed in 1.1), which
is basically some errors are not "perl-errors", but C++ errors, and hence cannot
be caught with eval. The patch in ticket #230 can also be used on 1.0.x, so you
can fix your own 1.0.x version of Search::Xapian to be able to catch these errors.
