版主救命，配置不了打印机了，原来都是好的。

我升级了内核2.6.0-test9。
然后又在RH-net上自动升级，升级是kdelib及kdelib-devel两个rpm没成功。后来我的计算机就找不着SamSung并口ML-1210激光打印机，以前在升级内核后都是好的。
但现在一配置打印机时出现下列错误：
Traceback (most recent call last):
  File "/usr/sbin/printconf-gui", line 7, in ?
    import queueTree
  File "/usr/share/printconf/util/queueTree.py", line 927, in ?
    queueTree()
  File "/usr/share/printconf/util/queueTree.py", line 101, in __init__
    if cups_import.import_needed ():
  File "/usr/share/printconf/util/cups_import.py", line 200, in import_needed
    which = which_spooler ()
  File "/usr/share/printconf/util/cups_import.py", line 195, in which_spooler
    return which
UnboundLocalError: local variable 'which' referenced before assignment

怎么办？
