Description of problem: Segmentation fault when using tuxstat. Version-Release number of selected component (if applicable): tux-2.2.9-1 How reproducible: Run tuxstat. Steps to Reproduce: 1. Run tuxstat. Actual results: Segmentation Fault Expected results: Information about running tux threads Additional info: Random information. I don't know if this comes back as useful or not, since I'm not a programmer.
