New crash information added by DrKonqi

konsole (3.0.1) using Qt 5.4.1

- What I was doing when the application crashed:

I closed the application with the X (cross) button. The application only does this when not in a maximized state. Reproducible every time.
The application does not recognize the custom size settings even when the "keep last position" setting is turned off. As a workaround, I have turned that setting on, the application will now come up at the last size but crashes on closing when not maximized. The terminal command 'exit' works as intended with no crash.

- Custom settings of the application:

I have customized size, buffer, and font settings.

I'm getting a very similar crash. Often reproducible:
* Open Konsole
* start top
* Close Konsole with cross close
* Konsole tells you that top is still running
* "Close current Tab"
* "Top is still running..." -> Yes
* Konsole crashes about 1 out of 5  times.

What takes to move this bug from "unconfirmed" to "confirmed"?

I Just filed:

Bug 354028 - Konsole crash on exit ( yet another dupe of Bug 346833 et al because Dr. Konqi is broken.)
