-- Information about the crash:
I was opening 10 tabs, and was copying the input from tab 1 to all other tabs .. Then I want to disable this, so went to "Edit -> Copy input to - > none" but I noticed that it was still copying the input, so I did it again and then konsole suddenly crashed.

 -- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
