Code:
3/10/13 7:42:02.848 PM QuickTime Player[13422]: It does not make sense to draw an image when [NSGraphicsContext currentContext] is nil. This is a programming error. Break on void _NSWarnForDrawingImageWithNoCurrentContext() to debug. This will be logged only once. This may break in the future.
This appeared in my console when trying to play a MOD file - which, for some odd reason, QuickTime Player thinks it can play (but it actually can't).
