Description of problem:

system-config-display crashes immediately with:
Traceback (most recent call last):
  File "/usr/share/system-config-display/xconf.py", line 318, in <module>
    verbose(_("Trying with card: %s") % current_card.getDescription())
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 4: ordinal
not in range(128)

Version-Release number of selected component (if applicable):
system-config-display-1.0.51-8.fc9.noarch
rhpxl-1.2-1.fc9.x86_64

How reproducible:
always

Steps to Reproduce:
LC_ALL=cs_CZ.UTF-8 system-config-display

Actual results:
The utility crashes with the above traceback.

Expected results:
system-config-display's dialog appears.

Additional info:
The Czech translation of "Trying with card: %s" contains non-ASCII characters:
"Zkouším kartu: %s". The translated string is of Python type 'str', but the
string returned by getDescription() is unicode. Python wants to convert the str
to unicode, but expects only ascii and crashes.
A quick fix is to change the line to:
verbose(_("Trying with card: %s") % `current_card.getDescription()`)
