An alternative fix for report.py would be if there are no UserGroups DO NOT add the UserGroups field at all. Adding it with an empty string or whitespace is the problem. If it's not present at all apport-unpack will not throw the error.

[Regression Potential] We are just setting UserGroups to ' ' as opposed to having it be completely empty so there isn't any chance for regression.
