Description of problem:

When you open a kickstart configuration file, that has a "lang"
directive whose parameter ends with a locale charset, it is silently
ignored and default "English" lanugage locale is preselected in the
system-config-kickstart GUI. Anaconda creates configuration files
with such locale.

Version-Release number of selected component (if applicable):

system-config-kickstart-2.6.17-1.fc6

How reproducible:

Always

Steps to Reproduce:
1. Create a configuration file with "lang cs_CZ.UTF8" line
2. Open the file in system-config-kickstart

Actual results:

English language locale was preselected.

Expected results:

Czech one should be selected.

Additional info:

When you save a configuration with Czech locale to a file, "cs_CZ" is
generated as an argument to "lang" directive.
