Access to admin/config/workbench uses incorrect permission

The patch applied cleanly and fixed the configuration section using the wrong permission.

Committed.

   6857511..f40e723  7.x-1.x -> 7.x-1.x

In workbench.module (7.x-1.2 version) I see this (as #1):

  $items['admin/config/workbench'] = array(
    'title' => 'Workbench',
    'description' => 'Workbench',
    'page callback' => 'system_admin_menu_block_page',
    'access arguments' => array('administer workbench'),
[......]

but is not working for me, as administrator.
I dunno why this isn't working. Any idea?

Have you cleared the cache / run update.php?

By "administrator" do you mean user 1?

Yep, both cache cleared and I ran update.php.
And, yes, by "administrator" I mean user 1, of course :)

Do you have any of the submodules enabled (Workbench Moderation, Workbench Access)? If not, this item won't appear because Workbench itself has no configuration.

Oh sh**! Sorry :)

Anyway, there is a usability problem in this: if you give the ability to access to a configuration page, but the configuration page doesn't have any configurations is better to follow one of the next options:
1) the configuration page has no sense to exists;
2) if you need to have the configuration page, is better display a message like "There aren't configurations at the moment" instead of an access error message.

Blame core's handling of configuration blocks. This works as designed.
