--- Comment #1 from James Luscher jluscher@gmail.com --- More research indicated that the crash was related to accessing the webcam.
I have an image (.png) of the details here: http://ubuntuone.com/26EJrLnsjM9NxS4FbbrJIq
The developer has responded that the next revision of Cura (14.02) is going to remove access to the webcam.
I will try the new version ASAP, which will hopefully, let me proceed with running the program - though it doesn't mean that any problem has been fixed :-(
