Dasher initializes, fails to find signal handlers in libglade, hangs

I can reproduce this every time on my dapper system. I have updated as of
today; reinstalled dasher, and ran it again. I originally dist-upgraded from
Breezy. 'Ellen' is a K7 machine. I am able to sudo with account broam.

This is dasher version 3.2.18-1

Output on starting from a gnome terminal in X11:
