- What I was doing when the application crashed: Building a house schema, I was editing properties of a line. I mix the coordinates, and loose the line.
I hit 3 times undo until the history hit a moving shape. 
At that moment I clic on redo, the action was done. but a few seconds later karbon crash.

-- Backtrace:
Application: Karbon (kdeinit4), signal: Segmentation fault
