Here is an oddity... running PS CC 20140730.r.148 on an iMac running OS X 10.9.4. Fonts are being managed by Suitcase Fusion 5.
As stated in the subject, I am getting a font error in a file where there are no fonts, let alone any layers other than the background.
Here is a screenshot of the offending file and the layers palette to show the supposed lack of fonts.

This has happened on a couple of images now. Any thoughts?
