Bug 418550

Application: labplot2 (2.7.0)

Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.4.20-gentoo x86_64
Windowing system: X11
Distribution: Gentoo/Linux

-- Information about the crash:
I tried to remove 2 columns from a spreadsheet, just after importing some data in it. LabPlot always crashes after I hit "remove columns" from the contextual menu.

The crash can be reproduced every time.

-- Backtrace:
Application: LabPlot (labplot2), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
