Komodo 4.0a2

Just installed Komodo 4.0a2 from ActiveState on my AMD64 system running Ubuntu Linux (AMD64 build).

I’m receiving this error when I perform certain functions, such as performing a CVS commit operation:

Note that this error occurs no matter if I start up Komodo using the menu item that was created by the installer or even if I use a startup script that utilizes the 32-bit pango libraries. Here are the contents of that startup script:

#!/bin/sh
export GTK_PATH=/usr/lib32/gtk-2.0/
export PANGO_RC_FILE=/etc/pango32/pangorc
/opt/Komodo-4.0/bin/komodo
