Bug#404482: Patch to fix the "I" cursor issue

[Attilio Fiandrotti <attilio.fiandrotti@gmail.com>]

package: cdebconf-gtk-udeb
severity: normal
tags: patch

Many users complained about the cursor remaining "I" shaped after 
passing on a question description (that's due to a minor gtk/dfb bug 
which still has to be fixed)
As a workaround, the attached patch resets the cursor to its original 
arrow shape when it moves into the main gdkwindow.

Merry XMas !
