Can't create new folder when bookmarking a page

When attempting to bookmark a page, I can't create a new folder...the new folder name gets accepted without me hitting the enter key. For example, attempting to create a "Firefox Sucks" folder results in a folder called "F" or "Fi" depending on how fast I type.

Steps to reproduce:

1- Go to a web page, preferably some pr0n.
2- Select Bookmark/Bookmark This Page
3- In Folder drop-down, select "Choose"
4- Click "New Folder" button
5- Type something longer than a few characters
6- Notice that a folder gets automatically created after typing in a few characters

Chris, if you don't fix this, I'm switching to mint!!
