I did some experiments and found out that the text will wrap only when I
change:

self.scrollWnd.set_policy(gtk.POLICY_NEVER, gtk.POLICY_AUTOMATIC)

to

self.scrollWnd.set_policy(gtk.POLICY_NEVER, gtk.POLICY_ALWAYS)

ie. when the vertical scroll bar is showing in the ScrolledWindow. The
solution of forcing a vertical scroll bar is ok for this scenario, but I ran
into another problem which is caused by the same thing. I have a TreeView
that uses ListStore in another ScrolledWindow, and I really don't want a
horizontal scroll bar to show up. However, by having it disabled the
ScrolledWindow seems to grow horizontally to fit the contents of the
TreeView, and it totally messes up the GUI. I don't want to have a
horizontal scroll bar here for aesthetic reasons.

Is there any way to make a ScrolledWindow to not expand to fit its contents?

Any help is welcome.
