Renaming Can Produce Error

[Nicholas-Westby]

I installed Bookshelf, then tried to rename the book that it installed by right-clicking it and selecting the "Rename" action. Then, I clicked the "Rename" button without changing the name and got this error message:

That's probably because it's trying to rename the folder to the same name as it already has. Might be worth checking against the original name before attempting to do the rename. Perhaps you could even disable the "Rename" button if the new name is the same as the original name.
