Doesn't crash for me, I wonder what's different on your machine. Do you have any custom commands configured?

[crazytaxi824]

I tested it again. I have set some of the keybindings to null. When the search result hits the one with null keybindings, it crashes.

[Stefan Haller]

Ah, thanks, easy to reproduce. Here's a fix: #3450.
