PATCH: Explorer crashes if file is not renamed

Using latest trunk + Vbox 4.02, no additions installed

How to reproduce:

Start ROS, click only once on the Command Prompt icon(or another one if you want), wait a second and click once again(single click), and the filename should be editable now.
Don't modify the name and don't press enter, just click on the desktop and the icon of the file disappears. Now click with the right button of the mouse and explorer crashes, and whole system will be unusable, only mouse can be moved

This is the log:
