When you delete a folder, you are unable to delete another folder with the same name, unless you empty the Trash.

The message you get is:

"A folder with that name exists. Please use another name".

The error message is a little confusing. According to this message, you will first have to rename the folder, before you can delete it."

Reproducible: Always

Steps to Reproduce:
1. Create a folder X
2. Create a folder Y
3. Create a subfolder of X, named 01
4. Create a subfolder of Y, named 01
5. Delete the subfolder 01 from X
6. Delete the subfolder 01 from Y
7. Here comes the message!
Actual Results:  
The following message pops up:

"A folder with that name exists. Please use another name".

Expected Results:  
Just let this folder be moved to thrash. Do not check the name (use another internal name perhabs, but keep the same display name). You should be able to delete subfolders with the same name, not?
