Description of problem:

yum update --skip-broken with Czech locale (cs_CZ.UTF-8) fails with:

Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode characters in position 4-5: ordinal not in range(128)

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

yum-3.2.27-4.fc13.noarch

Changing "str(e)" to "unicode(e)" on depsolve.py:275 solves the problem, though I'm not sure if this is the proper solution.
