Description of problem:
-------------------------------
On Phoebe2, I get the following error logged to the console when trying to
configure a Networked Windows (SMB) printer:

Traceback (most recent call last):
  File "/usr/share/printconf/util/addQueue.py", line 822, in smb_specify_clicked
    machine, sharename = match.groups ()
AttributeError: 'NoneType' object has no attribute 'groups'

Version-Release number of selected component (if applicable):
----------------------------------------------------------------------------------
redhat-config-printer-0.6.37-1

How reproducible:
-------------------------
Always (only seems to happen with SMB printers and not CUPS/IPP printers)

Steps to Reproduce:
----------------------------
1. Open a terminal
2. Su to root
3. Run "redhat-config-printer"
4. Choose to add a Networked Windows (SMB) printer.
5. Click the "Specify" button to enter the following authentication information
(don't mind if the host, username or else are invalid):
6. Leave Workgroup blank.
7. Enter a valid host name for a Windows print server
8. Enter a valid queue name
9. Enter a Username that contains blank spaces (in my case, it was "Felipe
Alfaro Solana")
10. Enter something as Password
11. Click OK
12. The error message described above is logged to the console and the operation
fails.

Actual results:
--------------------
Can't add a Windows printer.

Expected results:
-----------------------
Some Python problems appear to  keep me from adding a Windows printer.
