OF Log Error: ppleDouble/ (AppleDouble?)

Project written in oF, migrated to iPhone oF (007). I get a string of log errors:

  
OF: OF_LOG_ERROR: ppleDouble/  

One for every call to

  
testApp::draw()  

. Anyone else seen this? I can find nothing in the forums, docs, google… Looks like it’s trying to say “AppleDouble” but a project search for “AppleDouble” or just “ppleDouble” returns no results in Xcode.
