Application: calligrawords (3.1.0)

Qt Version: 5.10.0
Frameworks Version: 5.45.0
Operating System: Linux 4.13.0-39-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed: Deleteting two page-centered spaces below a table, crash resulting after deleting the second (last) space below the table. This error reoccurs after I open the recovered document and repeat the action.

- Custom settings of the application: Kvantum theme engine, global file menu, Window Width: 939 Width: 678, Add object applet docked to the right and collapsed, Primary? applet/section docked to the right under it and expanded. I was editing on the second page at the time. The table was split with two rows of cells on the second page.

The crash can be reproduced sometimes.

-- Backtrace:
