I enter in System configuration > Account details and when i try to edit the name's entry, click on "Apply" button and put my password (tried root password too) the window freezes, allowing only to click on buttons on the upper right (minimize, maximize and close). If I click on close button, will ask if I want to kill the process or wait. The other windows that could be opened works normally, as the system.
When I try "chfn" command in terminal, works perfectly, allowing me to change the name's entry.

Steps to Reproduce:
1.Enter System Configurations
2.Enter Account details

4.Click on "Apply"
5.Enter password

Freeze the window of Account details.

Expected Results:  
Not freeze the window and allow to edit again (if I wish to) or get back to main screen of System configuration.
