The older Krita 4.2.9 compiled on the same system does not segfault.

Krita Git master as of today crashes as well with a (slightly) different output.

Comment 1 Halla Rempt 2021-11-10 12:52:48 UTC
It would be better to build without so many packages disabled... You're definitely going to run into trouble. I suspect that this patch will fix the issue, but I am not going to create a build like yours to test this out:

diff --git a/libs/widgets/KisVisualColorSelector.cpp b/libs/widgets/KisVisualColorSelector.cpp
index 8cb62bc2fb..c2f5c5689d 100644
--- a/libs/widgets/KisVisualColorSelector.cpp
+++ b/libs/widgets/KisVisualColorSelector.cpp
@@ -94,8 +94,9 @@ void KisVisualColorSelector::slotSetColorSpace(const KoColorSpace *cs)
         const KoColorSpace *csNew = cs;
 
         // PQ color space is not very suitable for selecting colors, substitute with linear one
-        if (cs->colorModelId() == RGBAColorModelID &&
-            cs->profile()->uniqueId() == KoColorSpaceRegistry::instance()->p2020PQProfile()->uniqueId()) {

                     colorSpace(RGBAColorModelID.id(), Float32BitsColorDepthID.id(),

Please check whether this works.

Thanks for the immediate nearly instant help, you're awesome! Sorry that I couldn't get back to you as fast as you came up with the patch, Krita takes a while to compile on my machine(s). I can confirm that the patch you've provided fixes the issue.

I disabled as much as I could for testing purposes, however as Exherbo is a source-based distribution like Gentoo we offer a few options to enable/disable optional features on compile-time.
Comment 3 Halla Rempt 2021-11-10 14:52:02 UTC
Cool, I'll push the patch.

Git commit 17a3a4c25ff686aec09033bac12d04e43ca03cbd by Halla Rempt.
Committed on 10/11/2021 at 14:52.
Pushed by rempt into branch 'master'.

Check pointers before derefencing.

This fixes a crash on startup if a whole lotta optional deps are
disabled.
