Jörn, No, I definitely had not updated Manjaro between the last successful launch of darktable, and when it failed.
As for the contents of /etc/fonts/fonts.conf, I don't appear to have either the directory or the file.... *cd ~/etc cd: no such file or directory: /home/audio2u/etc* There IS a fonts.conf file in my Home directory though. Its contents don't extend to line 29, though. Here are the contents of that file: *<?xml version='1.0'?><!DOCTYPE fontconfig SYSTEM 'fonts.dtd'><fontconfig> <dir>~/.fonts</dir> <match target="font"> <edit name="rgba" mode="assign"> <const>rgb</const> </edit> </match> <match target="font"> <edit name="hinting" mode="assign"> <bool>true</bool> </edit> </match> <match target="font"> <edit name="hintstyle" mode="assign"> <const>hintslight</const> </edit> </match> <match target="font"> <edit name="antialias" mode="assign"> <bool>true</bool> </edit> </match></fontconfig>* No, I did not mount a camera, although I MAY have had a USB key attached at the time. Not sure now. Attempting to launch darktable with camera control disabled yielded this: *darktable -d camctl This GDB supports auto-downloading debuginfo from the following URLs: <https://debuginfod.archlinux.org <https://debuginfod.archlinux.org>>Enable debuginfod for this session?
