According to the changelog, this bug was addressed and fixed in v1.5.1.. However I am using the LATEST and GREATEST, and I can report for sure that this has not been my experience in at least the LAST 3 versions of this plugin.. So before I use a CSS style or the widget.php hack posted (which is an ALL or NONE solution -- not what I want), HOW do I get my widget title to NOT display when I leave it blank???
V1.5.1 - 23.03.2010
Bugfix : PHP4 compat issue for Add gallery & options page
Bugfix : Gallery widget can now have a empty title
