New text open for writing
opened autocorrection menu for addding a new pair (cosi->così) 
tried to resume editing without clikking ok on the OK button
calligra crashed.

I tried to continue writing without closing autocorrection menu, couse was the first time I was using calligra on a new installation. So having many auto corrections to add I  thougt was better keeping the autocorrection form open so to not call it at any new word to add.


Reproducible: Sometimes

Steps to Reproduce:
1. opened autocorrection menu for addding a new pair
2. tried to resume editing without clikking ok on the OK button


Actual Results:  
calligrawords cashes

Expected Results:  
should permit continue editing my text
