** Description changed:
+ [Impact]
+ This causes the colord daemon to crash when a user with a username containing
characters not in [a..z][A..Z][0..9] logs in. Since we use usernames with a ‘-’
in them in Ubuntu for the guest session (and possibly in Ubiquity?), this is a
fairly common crash to hit.
+
+ It results in (among other things) display calibration (either applying
+ existing profiles, or attempting to generate a new one) failing to work.
+
+ [Test Case]
+ Log into a guest session. colord will crash, due to the username being
guest-$SOMETHING
+
+ [Regression Potential]
+ Low. If regressions appear, they're likely to be crashes rather than bad
behaviour, so they should be obvious.
+
+ [Original report]
+ crashes at startup
