Subject mod_negotiation:find_lang_index() segfault
Date Tue, 01 Jan 2002 16:23:02 GMT
CVS HEAD, request sent to protected page...  my configuration may be
bogus, as I'm trying to migrate a site running Apache 1.3.9 to Apache
2.0...

here is some basic information...  I don't have any time to look into
it at the moment...

Program received signal SIGSEGV, Segmentation fault.
