Can't delete a website which is duplicated in a folder

I can’t seem to delete a website which appears 2 times in a folder. In Firefox 21 I get the following error:

TypeError: a is undefined   
Line 1184   

The website in question is called “The Venus Project” in my account, if you need to take a look and reproduce.

You should be able to delete a dupe feed. I logged into your account and deleted the dupe with no issue. Hmm, wondering what could have caused it.
