There is no trojan. My guess is either this is yet another false positive or simply heuristics guessing because it is not a so-called "common file".
At this time, my current process is to send files to Virustotal when I first upload them, send out any false positive claims that immediately appear and then don't bother again because the AV engines constantly change and it really never ends.
As I regularly deal with these claims, my answer is pretty simple - if you don't trust it, don't run it.
Just for some thought though, this is open source, freeware, non-ad supported, beta software that's used by less than a handful of people that doesn't even have an installer, nor has/needs Administrator rights. There would be no advantage to putting malware in such software.
