Possible bug bad xmp profile

[fmw42]

In ImageMagick 6.9.10.49 or 7.0.8.49 and GS 9.25 and libjpeg 90, I am getting a report of a bad xmp profile when converting an AI file to JPG. If I convert to png, I do not get that error. I am not sure if this is an ImageMagick issue or a Ghostscript one.

AI file:
http://www.fmwconcepts.com/misc_tests/GRID2.ai

AI to PNG:

Code: Select all

convert -colorspace sRGB GRID2.ai x.png

Unfortunately, we cannot reproduce the problem. Try with the latest Beta release of IMv7 -50. Post the exception so we know which line exports the warning. Also post the output of `convert --version`.

OK. Using IM 7.0.8.50 beta on Mac OSX Sierra, I get

Perhaps you could test on your Mac.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

Thanks. This appears to be fixed in IM 7.0.8.50 proper.
