If any of you are still seeing this error on running sealert after the latest updates :

Traceback (most recent call last):
  File "/usr/bin/sealert", line 692, in <module>
  File "/usr/bin/sealert", line 112, in run_as_dbus_service
    app = SEAlert(user, dbus_service.presentation_manager,
  File "/usr/bin/sealert", line 326, in __init__
    from setroubleshoot.browser import BrowserApplet
  File "/usr/lib64/python2.7/site-packages/setroubleshoot/browser.py", line 46,
in <module>
    import report.io.GTKIO
ImportError: No module named GTKIO


please install report-gtk :

 yum install report-gtk 

That should fix it.
