-- Information about the crash:
I had selected multiple cells by Ctrl-clicking on their right edges with the mouse, right-clicking on the right edge of a selected cell, and choosing 'delete cells'. Cantor often (but not always) crashes when I do this.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Cantor (cantor), signal: Aborted
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
