OS X Unable to load libmediainfo.0.dylib

I get a lot of errors like this in my scanner logs:

MediaInspectorMediaInfo: unable to cast 'Unable to load libmediainfo.0.dylib'

followed by:
MediaInfo and FFmpeg disagree on the number of video streams in the file (ffmpeg: 1, mediainfo: 0)
MediaInfo and FFmpeg disagree on the number of audio streams in the file (ffmpeg: 1, mediainfo: 0)

Which of course is expected if it could not load the dylib

I can see that I have libmediainfo.0.dylib within the frameworks directory of the app

So why can it not load it?

Is this a bug?
