Coreutils (rm) does not allow a user to remove files within non-writable directories. However, gnome-vfs does allow a writable directory containing a non-writable directory containing a file to be moved to the trash. This phenomenon should be checked for even if it produces a slight overhead.

Example:

cd
mkdir -p test/test
touch test/test/file
cd test
chmod -R a-w test
cd
rm test/test/file

rm: remove write-protected regular empty file `test/test/file'? y
rm: cannot remove `test/test/file': Permission denied

To show this is only a folder permission problem, another example:

cd
touch file
chmod 000 file
rm file

No errors.

These folders/files should not be allowed to be moved to the trash.
