Binary package hint: serendipity

i just tried to install serendipity using synaptic on 9.04 AMD64. Debconf asked me if i want to configure a database for it. I chose sqllite which somehow failed(maybe because it ain't installed?) then i went "back" in the wizard and the crash notification appeared...

some more output from within synaptic:

dbconfig-common: writing config to /etc/dbconfig-common/serendipity.conf
*** WARNING: ucf was run from a maintainer script that uses debconf, but
             the script did not pass --debconf-ok to ucf. The maintainer
             script should be fixed to not stop debconf before calling ucf,
             and pass it this parameter. For now, ucf will revert to using
             old-style, non-debconf prompting. Ugh!

             Please inform the package maintainer about this problem.
