GtkTextSearchFlags is not an enum type

Various people have reported this error

** (0launch-gui:3347): WARNING **: `GtkTextSearchFlags' is not an enum type

This is not a bug in ROX; it affects all programs using PyGTK.

Upgrading your pygtk (or gnome-python) package should solve it. Also check that you don't have an old version of pygtk installed in /usr/local.

It appears that the bug was fixed in the PyGTK 2.2.x series.
