I did a cold shutdown and power up, and so far its doing better. I'll see if it decides to act up again. Fingers crossed.
I think it will do it again for you...I'm having the same problem. I have _not_ rooted, but I have installed Google Maps, Google Drive, Google Mail, Google Maps, and Google Play Books...along with the Google Framework and Google Login. I just noticed this behavior today.
Yesterday I was able to get the Google Framework working with my apps by installing Google Framework and then reinstalling all of the apps that started not working. I'm wondering if it is having Google Framework on the KFHD. I needed Google Framework to get Google Drive working (which is working quite well now).
Be nice to get the status bar back. When I shut down (not sure how to do a reboot), the status bar shows up. Then after a while...it goes away again.
UPDATE: It seems that after I shutdown and restart the notification bar is fine until something tries to write to it. So whenever I get a new notification, it seems to crash the notification bar. I did install USAToday last night. I've uninstalled Google Framework this morning and I'm getting the same behavior. It would be nice to know what is causing it.

I uninstalled in the following order:
1) Google Framework
2) UsaToday (since I just downloaded it last night)
3) google Drive
4) Google Mail (when I uninstalled this my notification bar _magically_ came back and has been working ever since.
I don't have time right now, but I will probably reinstall everything to see if I can reproduce the issue and then see if running GMail fixes the issue. I noticed that something was doing a notification which caused the bar to disappear. I wonder if it was some issue with Gmail.... I'll report back later tonight...unless someone else with the issue can verify things.
