The new fix of setting remote_background to True and
adding an & in the "simplier command" case can't work.
 If remote_background is True, then the first os.system
call will always succeed and thus the second one will
never be called.  So if the web browser isn't already
running, it will never start up.
As I alluded to in my previous bug submission 1338995,
the real fix will involve using the subprocess module
-- I will try to find some time to develop and test a
patch and submit it.
