Yuv, I too am having this problem (annoyance), and it also cropped up for me only recently, but more like several months ago. Coincidentally, I'm also a Hugin user. (recognized your name from the Hugin-PTX list) I did find this: http://www.imagemagick.org/discourse-server/viewtopic.php?f=7&t=6491 Which explains things, basically, but not very satisfactorily. Specifically, it seems that it's a function of the TIFF library used by ImageMagick, and the convert command is just passing the warning through. Of course, there's no way to turn that off through convert (would we want to?). So did the TIFF library change, did ImageMagick change the way it handles warnings from libraries, and/or did Hugin (and its TIFF library) change/add the 'TIFFReadCustomDirectory' tag to the tif files it creates? I'm using the command: convert image-stitch.tif -background white -flatten -trim -quality 90 image-stitch.jpg with ImageMagick 6.4.2 and libtif from MacPorts on OSX 10.4.11 (PPC).
