Hello @Martin2 ,
The version of G’MIC installed here (2.9.1) is quite old (like 4 years ago) and not maintained anymore. The .gmz file format used by G’MIC to store data (like in your case the CLUT data) has evolved since then, that explains the error.
Could you please try installing the latest release (3.5.0) and see if that fixes your issue ?
We don’t provide binary packages for Manjaro though, so I’m not sure how easy it could be to install the newest version for Manjaro. Maybe try recompiling the plug-in, using the instructions provided here? G'MIC - GREYC's Magic for Image Computing: A Full-Featured Open-Source Framework for Image Processing - Download
The best would be that the maintainer of the package update the version of G’MIC to the latest one. Maybe you can ask for it.
