Description of your problem

Spyder crashes after using the Run settings dialog for a first time run, on existing or new scripts.

What steps will reproduce the problem?

1. In Run preferences, tick the "Always show Run settings dialog on a first file run" box.
2. Attempt to run a script for the first time on the Ipython console.
3. On the Run settings dialog, select "Run in current Ipython console" and confirm.

What is the expected output? What do you see instead?
Program does indeed run but the "python.exe has stopped working" window appears and spyder is forced to close.

Please provide any additional information below
On the Run preferences, default working directory is the script directory. Spyder does sometimes crash when also modifying the Run preferences.
