I simply forgot about this old bug. I don't think it's still relevant: $ objdump -T /usr/lib/x86_64-linux-gnu/libgif.so.7.2.0 | grep GifQuantizeBuffer 00000000000069d0 g DF .text 0000000000000707 Base GifQuantizeBuffer Right?

Good morning, Upstream giflib has dropped the symbol. The Debian packages have been patched to re-introduce it. So no, this bug is still relevant. cu Andreas -- `What a good friend you are to him, Dr. Maturin. His other friends are so grateful to you.' `I sew his ears on from time to time, sure'

The Debian packages have been > patched to re-introduce it. Oh, thanks for the pointer. I took a closer look and it's an obscure feature lost which is already marked as experimental and basically unused. GNUstep upstream is aware of the change in giflib. To verify, I rebuilt giflib with revert-GifQuantizeBuffer-remove-from-lib.patch giflib_quantize-header.patch removed and GifQuantizeBuffer deleted from the .symbols file. Then rebuilt gnustep-gui and installed the library package. Viewing GIF files with preview.app and price.app works and that's what is important. So you can safely exclude gnustep-gui from the list of problematic packages that are affected by this change.
