Description of problem:
Please have messages replace others which are precisely the same thing; it's quite confusing to be trying to close windows and not have them close when you're trying to do so. It looks like it's because there's multiple which are the precise same thing. If they are all giving the same data (that there are new selinux errors), there is no reason to have multiple windows.

Version-Release number of selected component (if applicable):
2.0.5-3

How reproducible:
Always

Steps to Reproduce:
1. Have multiple setroubleshoot errors causing multiple messages to the screen
  
Actual results:
Multiple error messages popping up

Expected results:
Single error message, since they all say the same thing (that there is a new error, not what the error is)
