comment:        I installed Adobe Flashplayer from get.adobe.com/flashplayer.  I closed Firefox, but noticed that it still showed Firefox in the taskbar.  Firefox was closed, and I confirmed so by doing ps aux.  Clicking on the firefox taskbar entry didn't do anything so I decided to relogin.  The system crashed immediately after I logged out of the machine, so I did a hard reset.

Comment 1 Pontus Enhager 2011-11-13 08:45:08 UTC 
this seems familiar - i think i saw this too in a similar fashion
Comment 2 Noel 2011-11-19 04:54:29 UTC 
I believe this is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=751753 - you could perhaps close this one, and go to that one to star it, helping the devs to focus on a fix.
