Comment 9 for bug 1289411

Trusty box fully updated.

Steps to reproduce the bug:
Click Menu icon and navigate to Settings Manager -> Desktop.
Click on the 'Help' button of the Desktop Settings dialog.

Expected behavior:
Xfdesktop online documentation should open web browser at http://docs.xfce.org/xfce/xfdesktop/4.11/start.

Actual beahavior:
Help button isn't triggering the expected opening of the online documentation. In fact there's apparently no click event associated with the said button.
