Caused by:

ID pointer types should not be used by operators as we can't store the settings for re-use, or stored in keymap preferences.

As far as I can see, this should be disallowed by the API.

I'll commit a workaround for the crash, however using ID's in operators should be avoided (we can discuss alternatives in chat).
