trac-admin problem with Ubuntu bundled version (0.9.3)

[Andy Buckley]

I've been seeing the following problem with the trac-admin command from
the Ubuntu Dapper Universe package repository:

----
andy at dirac:~$ sudo trac-admin /var/trac/andy initenv
Creating a new Trac environment at /var/trac/andy

Trac will first ask a few questions about your environment
in order to initalize and prepare the project database.

  Please enter the name of your project.
  This name will be used in page titles and descriptions.

Project Name [My Project]> Andy

  Please specify the connection string for the database to use.
  By default, a local SQLite database is created in the environment
  directory. It is also possible to use an already existing
  PostgreSQL database (check the Trac documentation for the exact
  connection string syntax).

Database connection string [sqlite:db/trac.db]>

  Please specify the absolute path to the project Subversion repository.
  Repository must be local, and trac-admin requires read+write
  permission to initialize the Trac database.

Path to repository [/var/svn/test]> /svn/andy

  Please enter location of Trac page templates.
  Default is the location of the site-wide templates installed with Trac.

Templates directory [/usr/share/trac/templates]>

Segmentation fault

Has anyone else seen the same problem? And fixed it? :) Any ideas? A
starter would be if there's a way to get a traceback of some kind rather
than just "Segmentation fault". Here's the package info:
