I'm not sure if I had the same problem. I was trying to install Bacula on Hardy, and it failed around this point:
Unpacking bacula-fd (from .../bacula-fd_2.4.2-1ubuntu4~hardy1_i386.deb) ... Selecting previously deselected package bacula-traymonitor.

It turned out that I had a "bacula" user but no "bacula" group; after adding one, the package installed fine.
