Description of problem:
Python TypeError
modules/create_user.py in isUsernameOk
self.showErrorMessage(_("The user name '%s' contains whitespace. "
TypeError: not enough arguments for format string

I was trying combinations of bad user input and this is the only problem I
noticed so far.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. run firstboot from the command line /usr/sbin/firstboot
2. at the user setup, enter a user name with whitespace in it
3. click forward and you'll see the error modal box
    

Actual Results:  Modal error box comes up:
modules/create_user.py in isUsernameOk
self.showErrorMessage(_("The user name '%s' contains whitespace. "
TypeError: not enough arguments for format string



Expected Results:  error message box saying you can't have whitespace in a user name

Additional info:

I'm not sure what the problem is, but when I did a copy and paste from the code
to produce the error message below the check for whitespace (checking for
punctuation in the user name), the problem was fixed. I don't understand what
you're doing with these multiline strings (me, I'd use the triple-quoted
strings), maybe it's an indentation thing too.
