lernid crashed with TypeError in _update_url_combo(): object of type 'NoneType' has no len()

[John S. Gruber]

Binary package hint: lernid

Happened after someone entered a "let me google that for you" url. For example, reproduce with Event->Open url with url http://lmgtfy.com/?q=gmail. This causes an (annoying) traceback / apport dialog, but doesn't crash or hang lernid, which continues to operate. A second url should be tried as well: http://www.alsa-project.org/alsa-info.sh

To reproduce start a session and use the Event->Open URL option with, for example, the following URL:

http://www.alsa-project.org/alsa-info.sh
