GtkProgress demo from tutorial not working on ubuntu hardy?

["Till Harbaum" <lists harbaum org>]

Hi,

i can't manage to get the activity mode of the progress bar to work
on a ubuntu hardy running gtk 2.12.9

Even the example from
  http://library.gnome.org/devel/gtk-tutorial/stable/x831.html

just makes the progressbar stop when i activate "Activity mode".
I was expecting it to show this blob bouncing forth and back, but
that doesn't happen.

Is/was activity mode broken? I'll try this on a different machine.

Till
