MIME-info database contains multiple entries for *.png, namely image/png and image/x-apple-ios-png. The later one doesn't have associated handler program, but this one is selected by mimeopen tool. Not sure how this tool should behave in case of multiple matches (IOW is it a bug in File::MimeInfo perl module used by mimeopen). Instead of switching to different tool, which probably will break other files (check #423), add override for this particular file type.
