gimp2 @2.8.14: failed to load "./cursor-color-picker.png": Couldn't recognize the image file format for file './cursor-color-picker.png'

[briank@…]

After having just done a selfupdate and upgrade outdated, I'm trying to install ufraw which requires gimp2. I didn't previously have gimp installed. After the compilation fail, I tried to sudo port clean --all gimp2 and then reinstall, but the error remains the same. From the install log:

tool-text-bw.png tool-zoom.png tool-zoom-bw.png; do \
:info:build 	    echo $image | \
:info:build 	      sed -e 's|.*/||' -e 's|-|_|g' -e 's|\.png$||' >> tool-cursors.list; \
:info:build 	    echo "  ./$image" >> tool-cursors.list; \
:info:build 	  done )
:info:build ( rm -f color-picker-cursors.list; \

:info:build 	      sed -e 's|.*/||' -e 's|-|_|g' -e 's|\.png$||' >> color-picker-cursors.list; \

:info:build 	  done )

I attempt to run the gdk-pixbuf-csource command myself, but still get the same problem.

In the error message (both when run by hand or when done via ports), it complains about the file cursor-color-picker.png. I can view that file with Preview - it looks like a color picker. I can identify the file with ports' ImageMagick.

Because I just updated, I have the most recent port of libpng if that matters:

$ port installed libpng
The following ports are currently installed:
  libpng @1.6.18_0 (active)

We have seen this type of thing before (#29393) but I don't know why it is happening to you now.

This ticket is six years old, and relates to a much older version of GIMP. If this is still happening, please reopen.

Closing.
