rested does not exit. Not reactive to Ctrl+C

When I click on Exit, rested does not exit, not showing any tb on the console output.

Going to the console and trying to close it with Ctrl+C doesn't works either. Instead, I get some tracebacks:

```

The rest editor only supports qt4 as toolkit. Toolkit changed to qt4.
