small GUI issue when trying to burn an image

1. Insert a blank CD-R (do this first, because when I do it when brasero asks for it, I do not get the bug...)
2. ALT+F2 brasero
3. Click on "Burn an image"
4. Select an *.iso file
5. Try to select your empty-CD-R

You should get a normal drop down menu, but instead the menu is blurry and cannot be selected (see screenshot).

Strangely, if you click the "Burn" button, your image will be correctly burnt anyway...
