gedit loses cursor when user rolls up its window

[Oleg Moiseichuk]

System description: Ubuntu 12.04 LTS with GNOME Classic (using Compiz); gedit version: 3.4.1-0ubuntu1

Steps to reproduce the bug:
1. Activate roll up behaviour for the windows using gconf: /apps/gwd/mouse_wheel_action = shade
2. Roll up gedit window into window header scrolling up over window titlebar
3. Unroll gedit window by scrolling down over window titlebar
After that document editing field loses focus and cursor. Focus can be returned when you click somewhere in the document, but cursor stays invisible and you cannot determine where it is located.

Workaround:
If you minimize, then restore back gedit window, then cursor reappears and behaves normally.

Status changed to 'Confirmed' because the bug affects multiple users.

I confirm the path to reproduce.

I found another, easier one.
1. Focus on gedit window
2. Press CTRL/R-ALT/SHIFT

Result:
Cursos becomes invisible when it's not moved. When it's moved it blinking.
