redhat-config-packages出现这样的错误

运行/usr/bin/redhat-config-packages之后就出现下面的错误


Traceback (most recent call last):
  File "/usr/share/redhat-config-packages/MainWindow.py", line 163, in ?
    comps = im.readCompsViaMethod(hdlist, progress.update)
  File "/usr/share/redhat-config-packages/method.py", line 488, in readCompsViaMethod
    update_method = update_method)
  File "/usr/share/redhat-config-packages/comps.py", line 387, in __init__
    self.readCompsFile(file, self.packages)
  File "/usr/share/redhat-config-packages/comps.py", line 471, in readCompsFile

  File "/usr/share/redhat-config-packages/comps.py", line 420, in setupStateDicts
