Threatfire keeps warning me that wuala is "logging keystrokes"

It has happened twice already. yesterday and today (i have installed wuala for over a week). threatfire considers it a high security risk. i've temporarily allowed wuala to run even though i can't imagine why keylogging is needed.

What could trigger this? Is it a false positive or is there some security issue we should know about?
 
sad I’m worried
Inappropriate?
