Bug#546837: A little more progress

[Dominique Brazziel]

	I corrected the way the command string was built
to take out the redundant braces but there is still that
pesky 'u' before the URL:

[   DEBUG:UpdateManager.Util.procesinfo] cls = <class
'UpdateManager.Frontend.Gtk.ChangelogViewer.ChangelogViewer'>
[   DEBUG:UpdateManager.Util.procesinfo] url =
u'http://bugs.debian.org/531668'
[   DEBUG:UpdateManager.Util.procesinfo] Proc: <ProcessInfo(pid=2661,
name=sh, owner_uid=0, parent_pid=2657)
[   DEBUG:UpdateManager.Util.procesinfo] Proc: <ProcessInfo(pid=2657,
name=gksu-run-helper, owner_uid=0, parent_pid=2647)
[   DEBUG:UpdateManager.Util.procesinfo] Proc: <ProcessInfo(pid=2647,
name=su, owner_uid=0, parent_pid=2642)
[   DEBUG:UpdateManager.Util.procesinfo] Proc: <ProcessInfo(pid=2642,
name=gksu, owner_uid=1000, parent_pid=2638)
[   DEBUG:UpdateManager.Util.procesinfo] pi.owner_uid is 1000
[   DEBUG:UpdateManager.Util.procesinfo] command = ['sudo', '-u#1000',
'gnome-open', u'http://bugs.debian.org/531668']
GConf Error: Failed to contact configuration server; some possible
causes are that you need to enable TCP/IP networking for ORBit, or you
have stale NFS locks due to a system crash. See
http://projects.gnome.org/gconf/ for information. (Details -  1: Failed
