Description of problem:
When I try to start the Printer Manager on Gnome, it doesn't start, so
I  execute it from terminal mode, and I get this messenge:

[root@RHES root]# redhat-config-printer
Traceback (most recent call last):
  File "/usr/sbin/redhat-config-printer", line 9, in ?
    import queueTree
  File "/usr/share/printconf/util/queueTree.py", line 945, in ?
    queueTree()
  File "/usr/share/printconf/util/queueTree.py", line 102, 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

Then I cannot set up or modify any printer, I try to use CUPS web
console, this make me setup a printer, but it prints only the first
middle of a sheet.

Version-Release number of selected component (if applicable):
redhat-config-printer-0.6.47.3.19-1

How reproducible:
Always

Steps to Reproduce:
1. Start Printer Manager from GUI
2. Start Printer Manager from text terminal
3. Kudzu reconize a new printer and tries to set it up but it blinks
the screen

    

Actual Results:  In all que cases it doesn't starts or show me the
error Tracer (copied in the last blocks)

Expected Results:  The programs can be executed and let me setup a
printer as easy as it used to do.

Additional info:

I believe this problem was generated by the last update I have
downloaded. Because I didn't change anything and I registered it when
we tried to change some propetires and the program doesn0t start
