The current version of qutebrowser (1.13.0, nixpkgs svn-revision: 234831.e97fdce4e1b) packaged in unstable fails to start with webkit backend.

Forcing the backend in the resulting error dialog does nothing.

To Reproduce
Steps to reproduce the behavior:

1. set c.backend = "webkit" in ~/.config/qutebrowser/config.py
2. start qutebrowser
