Summary: 4.2.9 Segfault in IccColorProfile::operator== on
Exherbo
Product: krita
Version: unspecified
Platform: Exherbo Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Color models
Assignee: krita-bugs-n...@kde.org
Reporter: griss...@nexusg.org
Target Milestone: ---
SUMMARY
Krita 4.2.9 segfaults when saving an image, only if another reference file
[which presumably has its own color profile information, or causes it to load]
is not opened first. More information in the backtrace:
```
Thread 25 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

The other file was likely made with another version of Krita, though I don't
know which--one used by a friend. I'd probably have to ask permission to post
it here, since it isn't mine. Files then successfully saved by this version of
Krita are not sufficient to prevent this segfault when opened in a fresh
session.
4.2.9 doesn't look like the latest, but 4.2.9-r1 is the latest Exherbo package
in ::kde. I haven't tested newer sources, but I could get around to that.
STEPS TO REPRODUCE
1. Create and modify any new file.
2. Save as a .kra file.
OBSERVED RESULT
Segfault, detailed in the backtrace above.
EXPECTED RESULT
A successfully-saved .kra file and no crash.
