Program.launch will first attempt to open files using libgio and then fallback to gnome-vfs. gio_launch uses g_file_new_for_path which fails when passed a URI. If swt was built with USE="-gnome" then the fallback fails as well, making it appear that a package has a dependency on swt[gnome] when it does not. Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library.
