When setting variables in the administrator editor, if you click CANCEL on the password request, Workbench hangs, and becomes unusable.

How to repeat:
Using MySQL 5.1 and WB 5.28.
1) open the administrator editor
2) Click on "configuration"
3) click on "log files"
4) check a few options
5) click "apply"
6) click "view file"
7) click "apply"
8) in the password dialog, click "CANCEL"

You will get a popup saying "Unhandled exception: 'NoneType' object is not callable".
After that, the application hangs, and is unusable forever, and doesn't quit. ("forever" = more than 10 minutes, or way more than any 21st century user is willing to wait)

Suggested fix:
Handle the exception

Probably related to Bug#49004 "Unhandled exception when clicking on 'Logs' button"

After 40 minutes, still hanging.

After 2 hours and 40 minutes, still hanging. I stopped it.

Restarted from the command line. The problem seems to be here:

 File "/Applications/MySQLWorkbench_5_2_8.app/Contents/PlugIns/wb_admin_config_file_be.py", line 121, in apply_clicked
    self.accept_action() # call action passed from caller(client)
TypeError: 'NoneType' object is not callable

An entry has been added to the 5.2.9 changelog:

n the Configuration tab of the Server Administrator screen, if log file configuration changes were applied, MySQL Workbench hung if the password request dialog was cancelled.
