Hi Brent,
the upstream for this program is Debian [1][2] for general bugs and/or
feature requests you'd use those.
While the Ubuntu bug tracker [3] would mostly be for issues due to the
Ubuntu Delta or to ask for backports of fixes into active Ubuntu
Releases as part of the SRU process [4].
Do these pointers help enough to enable you to take the next step
reporting [5][6] this?
