Reporter, can you give us more detailed reliable reproduction steps?

I'm sorry, but I wasn't expecting the crash, so I wasn't paying a whole lot of attention to what I was doing when it happened.  I had a few tabs open in Firefox -- gmail plus a couple of linux-related sites.  While these were open, I was customizing the top "panel" in the gnome desktop by copying some program icons from the application drop-down menu to the top panel.  I may also have been clicking on some of the standard notification applets there when the crash occurred.  I had also recently (30 minutes prior) installed the Adobe flash player plugin for Firefox, and it seemed to be working fine.  

Without more detailed info on how to reproduce it, this one may be a lost cause.  If it happens again, I'll try to document it better.

Thank you for your quick response. If the crash re-occurs, abrt should recognize that it is/is not the same. As it is, this back-trace alone is not specific enough to troubleshoot the root cause without being able to reproduce the crash. Closing for now. Feel free to re-open if you disagree with this determination.

Agreed... I wouldn't want to try to debug it without any way to reproduce it either :-)  Thanks.
