[Vala] [Vala/Clutter] ClutterText.set_single_line_mode() problem

[Brian Duffy <brduffy gmail com>]

Hi,

Vala 0.16-0.4.fc17
Clutter 1.10.6-1.fc17

Here I have a stripped down program to demonstrate a problem I am having
with setting a ClutterText to single_line_mode. If I do
mainMenuListItem7.set_single_line_mode(true), and
stage.set_key_focus(mainMenuItem7), then the text box works as I need it to
(single line mode), but for some reason, the ClutterText objects in the
listColumn actor don't have their background colors set properly when I
call the method to change the selected item.

The list items appear to be behaving as if I have set them to single line
mode even when I explicitly call xxx.set_single_line_mode(false) on them.

A text actor in single line mode will not wrap text and will clip the
visible area to the predefined size
