How odd! I hadn't noticed that things were working properly for Skia  
Regular. I've looked rapidly for a possible cause that could be  
triggering this:

- Presence or not of Regular in the name of the basic font shape.

- Location of the font files inside /System/Library/Fonts, /Library/ 
Fonts, or ~/Library/Fonts.

- Presence of a duplicate inside the Classic font folder /System  
Folder/Fonts.

- Format of the font file (.ttf, .dfont, etc.).

No luck: there doesn't seem to be any reproducible pattern. In case  
that would be specific to Apple Symbols, could it be triggered by the  
absence of alphabetic characters?

I don't know whether that has any relevance to the OpenType fonts. I  
have no such font to test for (is there any OpenType font shipped  
with OS X?). Was it the same error message that you were getting with  
Minion Pro?
