Logging in with wrong password raises a TypeError

[cd1]

When I type a wrong password when trying to log in to Kimchi, the following stack trace can be seen in the console:

This bug is always reproducible for me. It happens with "root", any non-root user and any non-existing user. Typing a wrong password seems to trigger the bug.

I am running Fedora 20 x86_64, Chrome 33.0.1750.117, libvirt-1.1.3.3-5.fc20.x86_64, Kimchi commit 5d82241.
