REVISION SUMMARY
  We need to return the absolute path instead of base name so decoColorToCombo
  can return the correct index.

TEST PLAN
  - Go to System Settings > Window Management > Window Rules;
  - Create a new rule for Konsole to force the Oxygen color scheme, close the dialog, and click the Apply button;
  - Open the rules dialog, click OK button, then Apply button.
  
  Without this patch, Breeze color scheme will be forced after the
  last step.
