Visual editor not working with Smart Slideshow Widget

I also have the same problem after upgrading to WP 3.5 with:
Text edit not being able to load, nor the link button or Edit the Publish immediately button.
I deactivated all the plugins and reactivated them one by one – Smart Slideshow Widget 2.7.4. caused the problem.

Thanks to joshguss there is a fix that might work for some:

And here is an alternative plug-in that works just as well: https://www.ads-software.com/extend/plugins/vslider/
