SEGV in request.c!apache_request_new in Request#lookup_uri

Apache: 1.3.34
Ruby: 1.8.4
mod_ruby: 1.2.5

When I use Request#lookup_uri, httpd dies with SEGV.

----
P.S.
I tried to report this incident via http://dev.modruby.net/tickets/new,
but it failed with following error!
| Application Error
| Sorry, but the following error seem to have occurred:
| Table 'collaboa_mod_ruby.statuses' doesn't exist: SHOW FIELDS FROM statuses

Backtrace follows:
