Unknown CORBA exception id: ‘IDL:omg.org/CORBA/INV_OBJREF:1.0′
What a wonderful informative message.
It happened when I logged into Gnome 2.6, once for each applet in the panel. Given the clarity of the message I had no doubt the applets didn’t load. I could also see they were missing in the panel 
After some searching I finally discovered the solution: log out of Gnome, remove /tmp/orbit-XXX where XXX is your username, and log in again. Problem solved.
One vote from me for intelligible error messages.

I agree totally! Thank you so much for posting this. Deep sigh! I couldn’t figure it out.

cool. I just updated everything and my email wouldnt open– havent rebooted yet since updates.. going to try this and hopefully all is well, TIA.

bravo! im back in business. Thought I could get away with just deleting and re-logging in, but that was scary and bad.
Rebooted, and all was good. Thx again.

I think you have to logout, delete from the console and login again. At least that was what I did.

After an attack by angry CORBAs, I limped around looking for an antidote for this snakebite. Bang. It’s like magic, I’m back together again! Thanks, Rene!

WOW!! A simple fix?
"Dorothy, I don’t think we’re in Windows anymore!!!"

Hmm! Nice work! But I wonder why the rpm packages don’t "know" about this!!! There’d be some lousy 5 lines to add!

Anyway, thanks very much for the help!

Thanks Rene. Great and simple fix.
Quick question though, what is orbit-separ for anyway?
I have other similar dir, should I delete them all? (kde-separ, mcop-separ, mc-separ, ksocket-separ)
As far as I know, you should not have anything relevant in /tmp.
thanks again,
seb
