            Bug ID: 442567
           Summary: crash EXC_BAD_ACCESS QList, QWeakPointer
           Product: krita
           Version: git master (please specify the git hash!)
          Platform: Other
                OS: macOS
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: * Unknown
          Assignee: krita-bugs-null at kde.org
          Reporter: ghevan at gmail.com
  Target Milestone: ---

Some crashes I encounter when launching krita. Some might be already fixed, and
some could be glitches as I could never reproduce them again. I paste the
backtrace in hopes of be certain the bug cannot happen again.
