Description of problem:
I can't seem to type anything in the preferences "excludes" tab and have
it take effect. Pressing the OK button does nothing, and if I close the
dialog in some other way, the excludes have not taken effect
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. bring up yumex preferences
2. click on excludes
3. type "freenx" as an example, and click OK.
nothing happens on OK
It should record my excludes list.
This is caused by a bug in yum, i have fixed it in upstream yum cvs, it will be
available in yum 3.2.1.
