Orca - 无法保存配置

我正在尝试更改 orca 设置（orca -s）上的语音人员，当我尝试单击“应用”或“确定”按钮时，控制台中会出现此错误：

Gtk-Message: 12:48:35.589: GtkDialog mapped without a transient parent. This is discouraged.
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/orca_gui_prefs.py", line 3054, in applyButtonClicked

    elif appSpecific == False and setEstablished == True:
UnboundLocalError: local variable 'setEstablished' referenced before assignment

我正在运行 Ubuntu 18.04.1 LTS 桌面。

知道问题可能是什么吗或我可以在哪里找到配置文件来手动修改它？

谢谢，朱利安

显然问题出在以下文件中：

/usr/lib/python3/dist-packages/orca/gsettings_backend.py

我设法在 Ubuntu 19.10 中解决这个问题，将文件移动到一个隐藏文件！

sudo su
cd /usr/lib/python3/dist-packages/orca/
mv gsettings_backend.py .gsettings_backend.py
exit
reboot

系统恢复后我就可以更改设置了！
