[Plugin: AddThis] Bug: Encoding of spaces, special characters in title

I have noticed so far that while the page or post title is correctly posted using the Facebook or Twitter functions (from dropdown toolbox or service buttons), using Favorites or the Email function results in titles with +s instead of spaces, %3A for colons, etc

In other words:
April 30: Open House at the Center
-becomes-
April+30%3A+Open+House+at+the+Center

I have tested it in on the homepage, a single post and page page. Using the email function, the Title is botched in the subject line by default; I created a new email template with the Title in the body and the same problem applies.

Additionally, I have noticed then when placing the function in my theme template (Atahualpa 3.4.6) –so that I may have AddThis at the top of each page + post in addition to the bottom– that the title + url are no longer correctly included; instead the home page title + url are used.
