the libicd_network_ipv4script file is invalid(the one without the period) you will have to sudo gainroot and open the libicd_network_ipv4.script in vi or leafpad and see what is in it.

This is the line that needs to be in that file:
run-parts -a "$1" /etc/maemo.dhcp.d

I know what happened you mv'd the dpkg file to the one without the period before script so that one contains the correct information with wrong file name but open it in editor to double check and if it does then you can do the mv command and make it to the proper file name to replace the original. You need to be root to move the file.
