Error message installing Google-Web-Designer

[Stephen Allen <marathon.durandal@gmail.com>]

Greetings.

Running Gnome-Shell 3.8.x on Debian Jessie, after installing
Google-Web-Designer the following message is presented:

	Setting up google-webdesigner (1.0.1.0-1) ...
	Error in file "/usr/share/gnome/applications/display.im6.desktop":
	"NoDisplay=true" is an invalid MIME type ("NoDisplay=true" does not
	contain a subtype)

Which results in the application showing up without any toolbars or
"chrome" just a blank shell.

Any idea what's wrong/needed to fix this? Google's page says it's
compatible with Debian/Ubuntu.

Thanks!
