PNG transparency issue IM 6.7.0.5 Q16

IM 6.7.0.5 Q16 Mac OSX tiger

Given the following image:



The following works fine if the output is gif:

convert boxes.gif -transparent white boxes_trans.gif




But creates transparency for the black instead of the white when the output is png.

convert boxes.gif -transparent white boxes_trans.png

The problem seems to exist with both Q8 and Q16 builds at least as far back as IM-6.6.6-1.
(but only with Q16 builds recently, at least from 6.6.9-6 and later)

Fixed in IM-6.7.0-7, SVN revision 4608.
