OS: Other
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]

SUMMARY
Specific sequence of UI inputs leads to a segfault.
I'm not sure if this is the same as/related to
https://bugs.kde.org/show_bug.cgi?id=502043, but it had a unique backtrace and
logic so I thought it was worth reporting.
STEPS TO REPRODUCE
1. Pin tab
2. Matrix
3. Click column one header
4. Click cell 2, 2
