** Description changed:

+ [Impact]
  Crash report and bug appeared straight after boot, cause unknown, though 
system went on to run normally after.
  Ubuntu 14.04 Beta 2
+ 
+ [Test case]
+ Set Firefox Nightly as default browser
+ UCC should not crash in that case
+ 
+ [Regression potential]
+ This is a null-pointer check, there's nothing to worry about.
