deepin20.2版   右键 -> rabbitvcs_svn -> 日志 -> 查看相对于前一个版本的差异，报以下错误

Note: 在deepin15.11版中可以正常查看差异

安装方式: sudo apt-get install rabbitvcs-core rabbitvcs-nautilus rabbitvcs-cli rabbitvcs-gedit

版本:

deepin15.11 (rabbitvcs-0.16.0, subversion-1.9.5,pysvn-1.9.4.0,configobj-5.0.6)

deepin20.2(rabbitvcs-0.16.0, subversion-1.10.4,pysvn-1.9.9.0,configobj-5.0.6)

错误(论坛今天上传不了图片), 见附件rabbitvcs_err.zip:

我有2台20.2的电脑，都出现此情况

搜了论坛，都没看到有这种情况，难道就我栽了吗

还是都不用rabbitvcs
