Description of Problem:

I think Nautilus should try to make files
modifiable before emptying the trash. For example,
if I copy the content of a CD on my desktop, it
won't have write authorization. If, later, I put
it in the trash, I won't be able to empty it
because I will lack the write permission.

I think a simple solution would to attempt to run
"chmod u+w -R" on the content of the trash before
emptying it. That way, if the user owns the files
in the trash he will be able to remove them, even
if they are read-only.

Steps to reproduce the problem:
1. Copy a data CD on your desktop
2. Move the folder into the trash
3. Empty the trash

Actual Results:

You get an error about you not having write-access
to the files in the trash.

Expected Results:

You should be able to empty your trash if it
contains files you own, even if they are read-only.
