non-object error message when running drush

Issue Summary

I was getting the following error message when I ran drush:
WD php: Notice: Undefined index: #node in custom_node_template_form_alter() (line 100 of
/var/www/sites/all/modules/contrib/custom_node_template/custom_node_template.module).

This may only be a php 5.3 problem but here's a suggested fix. Also, attached as a patch file.
