git-gui命令在macOS Sierra上崩溃

在升级至 macOS Sierra 后，git-gui 命令会崩溃并显示以下错误：

在AppKit中，NSScrollerImp _animateToRolloverState和__49-[NSScrollerImp _installDelayedRolloverAnimation]_block_invoke方法可能会导致NSException异常的发生。同时，Foundation库的__NSFireDelayedPerform方法以及CoreFoundation库的__CFRunLoopDoTimer和__CFRunLoopRun等方法也与此有关。在此异常发生时，git-gui会因信号6而终止。是否有其他人遇到过这个问题并且有解决方案？
