kubuntu 20.04 / Gimp 2.10.34 / gimp_gmic_qt 3.3.1
Using interactive color curves other than RGB and reopening in order to create a “fave” fails. The filter shows an error along the lines of:
*Error in ./fx_curves_interactive/*if/local/ *** Command ‘input’: Invalid argument ‘(0,0,59.4202881,32.3671494,100,100,-1,(…)53.623188,100,100,-1,0,0,100,100,-1,)’
Try and make a fave and that error is reproduced. This a 50 second demo that shows the problem.
I can fix it manually removing that final ,-1, from the parameter string. It has been like this for a while, pulling out some old versions 2.9.5 is OK but 2.9.9 not.
