       Priority:  Normal  |   Milestone:  Unspecified
      Component:  Sugar   |     Version:  Git as of bugdate

Distribution/OS:  Ubuntu  |  Bug Status:  New

 When the user writes a new username in the field, then after a given
 timeout a warning is shown in it, which says that to get the changes done
 one should restart the computer. When we change the name to the one that
 was the initial one, the warning should go away and the restart shouldn't
 be required, but still the warning is shown.

 Steps to reproduce the error
 1. Go to My Settings and then click the About Me option.
 2. Change the username in the field.
    * A warning is shown that a restart is required.
 3. Change the username back to the initial one.
    *The warning still remains there.

 I have attached the screenshots of the error.
 I am running on the latest sugar-build pull with a host system running on
 Ubuntu 13.10(64-bit).
