App "finish_installation" is asking for admin password

I got into work this morning and found a dialog box asking for admin credentials from an app called "finish_installation". I don't know where this came from or what caused it. I don't remember installing anything recently, certainly not yesterday. I could find very little about this on Google, only a few references to Sparkle and Soundvox, neither of which I use.

Does anybody here know what this is?
