With your new patches, I'm not experiencing any crashes, and the terminal displays the “cms!” message, confirming that it's working. Thank you. It also works when I use my own monitor color profile instead of the generic “sRGB.icc” and “WideGamautRGB.icc” files. Here's an example of the terminal output using my profile (Dell_1886_LUT_4.icc):

$ CIN_CM_PROFILE="/usr/share/color/icc/colord/Dell_1886_LUT_4.icc" /home/paz/cinelerra/cinelerra-5.1/bin/cin /home/paz/wide-gamut-tests/P3-sRGB-color-ring.jpg /home/paz/wide-gamut-tests/R2020-P3-color-bars.jpg

If you need the terminal with “loglevel=debug,” let me know.
CinGG also works when started from the KDE launcher—which was one of the things I suspected was causing the issue...

To include these features in the manual, I’d like to ask a few questions to clear up some doubts, but I’ll post them in a separate thread.
