Application: calligrasheets (3.1.0)

Qt Version: 5.12.2
Frameworks Version: 5.56.0
Operating System: Linux 5.0.2-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was performing a mix of cell merger operations and draw borders operations. It crashes from time to time so I save a lot in between. If one of the two operations caused a crash, then after reopening the file to perform the same operation, the program does not always crash. It is a hit or miss.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Calligra Sheets (calligrasheets), signal: Segmentation fault
