I'm trying to launch inkscape-0.92.2, but it segfaults:

Could you please add information on your OS?

Judging from the backtrace I suspect this might be a fontconfig issue.
Could you test a nightly build and see if it crashes, too? There was an issue where Inkscape crashed if fontconfig configuration was invalid or no fonts could be found for some other reason.

[L29Ah (zl29ah)]

Gentoo Linux here with customized fonts.conf that makes my favourite fonts preferred everywhere (nothing crashes tho).

Hiding ~/.config/fontconfig/fonts.conf makes it work. Attaching it.
