"Move File(s) to Folder" buggy without folder

1) Ubuntu 11.04
2) PPA
3) 1.3.1

Steps to reproduce:
1) Have an empty project.
2) Import one or several clips.
3) Make sure there is no folder in the "Project Files" tab in the upper left corner.
4) Right click on a clip and move the mouse over the "Move File(s) to Folder" option. A small out-of-place box should appear.

What should happen:
The "Move File(s) to Folder" option should be greyed out when no folders exist.

Patch below.

Also I don't think that the "Remove from Folder" option belong under the "Move File(s) to Folder" option, but that may just be me. The patch doesn't deal with that.
