Emtpy error message when trying to create a folder that already exists

[runboxdave]

I came across an error where if you try to create a folder with a name of a folder that already exists a notification pops up at the bottom of the screen that is empty. I suspect it is trying to say that the specified folder already exists.

I couldn't reproduce it: but the error message is awful nonetheless :D

Can you give me a Steps to Reproduce that makes it show an empty error? Is there anything in the JS console when that happens?

With Inbox highlighted as the active folder I tried to create a folder called Spam as well as a custom folder that already exists and I got the blank error. I wonder if it is browser specific. Let me check.

It doesn't appear to be browser specific. I've now got the same result in Firefox and Safari. I can't see anything particularly relevant in the web console or browser consoles, but I am not sure what I would be looking for.

The weird thing is that on production (runbox.com) the error message is empty, but when running the server from master locally, I get "folder_exists" in the message. Trying to figure it out.

Now the formatting is better, more readable to the user, but I really don't know why an error message appears when run only locally (for me at least). All the logs and results from API look the same so I really can't tell what's going on.
