--- Comment #2 from greg.hellings@gmail.com --- It's an old app which used to be Gnome-centric but has moved to cross-platform distribution lately. It still requires GTK2 and other older libraries.
Specifically the application is 'Xiphos' (http://xiphos.org). Until the past few months there was no ability to move off of GTK2 as there was no GTK3 build of webkitgtk available on Windows. I just cobbled together our first GTK3 build for Windows yesterday and it is fraught with bugs (although it works fine built against GTK3 on Linux).
