apt-get warning

[Patrick Dahiroc <patd@dahiroc.net>]

hi all

apt-get occasionally gives me the error below when i do an install or and upgrade

Global symbol "$idtoelt" requires explicit package name at /usr/lib/perl5/Debian/DebConf/FrontEnd/Web.pm line 199, <> chunk 3.
debconf: failed to initialize Web frontend
debconf: falling back to Gtk frontend
debconf: failed to initialize Gtk frontend
debconf: falling back to Dialog frontend

i see that i need to set $idtoelt to a 'frontend', but what is a 'frontend'? and what is the correct frontend to set $idtoelt?
