Unable to capture text from MultiLineEdit

[dmulder]

Here is some sample code, using yast-python-bindings.
If you run that against qt, all the text in the MultiLineEdit is captured and printed to the log:
/usr/lib/YaST2/bin/y2base ./MultiLineEdit.py qt

But if you run it against ncurses UI, only the first word is captured:
/usr/lib/YaST2/bin/y2base ./MultiLineEdit.py ncurses
