identify -unique doesn't work

According to the instructions when I run the program, identify is meant to return the number of colours in an image with the syntax identify -unique. However, while it recognizes the command, it doesn't return the number of colours and ImageMagick's output is the same as if no option were selected. It seems that the only way to return the information is using identify -format %k instead. Is this a bug?

Add -verbose to your command line.

Thank you! The command doesn't indicate that it requires -verbose; maybe that should be added to the documentation.

Its a bug. Look for a fix in the next point release of ImageMagick. Thanks.

In which release should -unique work? I have
identify --version
Version: ImageMagick 6.7.1-0 2011-07-26 Q16

Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC
Features: OpenMP HDRI
and it is not working. Just checking to see if it still is an open bug.
Thanks!
