Bug #49061 Manage Security causes error

Description:
Trying to use the "Manage Security" feature, I get an exception:

Traceback (most recent call last):
  File "C:\Program Files\MySQL\MySQL Workbench 5.2 OSS/modules\wb_admin_grt.py", line 199, in openSecurityManager
    tab.wait_server_check(4)
  File "C:\Program Files\MySQL\MySQL Workbench 5.2 OSS/modules\wb_admin_grt.py", line 95, in wait_server_check
    while tab.configuration.last_is_running_check is None and time.time() - t < timeout:
NameError: global name 'tab' is not defined

The second time I try to do the same thing, WB crashes.

How to repeat:
Try to "Manage Security"

Suggested fix:
Don't crash, do whatever "Manage Security" is supposed to do.

I think this is a duplicate of another bug report (from last week I think).

this has been fixed. will be included in 5.2.9

An entry was added to the 5.2.9 changelog:

Clicking on the Action Item, Manage Security, on the Home screen generated the following exception:

Traceback (most recent call last):
  File "C:\Program Files\MySQL\MySQL Workbench 5.2 OSS/modules\wb_admin_grt.py", line
199, in openSecurityManager
    tab.wait_server_check(4)
  File "C:\Program Files\MySQL\MySQL Workbench 5.2 OSS/modules\wb_admin_grt.py", line 95,
in wait_server_check
    while tab.configuration.last_is_running_check is None and time.time() - t < timeout:
NameError: global name 'tab' is not defined

Further, if this Action Item was clicked again then MySQL Workbench crashed.
