Drag a link to the clipboard frame raise error

[manuq]

Fixing the drag and drop issues in #3819, an error appears if a link is dragged from Browse activity to the frame.

TestCase

1. Open Browse. Navigate to a page with links.
2. Bring up the frame.
3. Drag a link to the frame.

The current code calls Python shutil.copyfile with the URL path, which obviously fails with "file not found".

I don't seem to reproduce the above error, everything works fine...

I am not able to reproduce the error. When I try to drag a link to a frame, it works fine for me and it's reopening too when I drag it back to the browser. Can you provide more details ?

I am running sugar-build on my host machine running Linux Mint 15 Olivia.(32 bit version).
