gnome-panel crashed with SIGSEGV in g_signal_emit_valist()

[Joe]

Not too sure what I'm doing here, This more or less opened up automatically and the summary was automatically generated as well.
I'm on 12.04 Beta, just updated, and I tried to install the ATI/AMD proprietary FGLRX graphics-driver (post release updates). After a restart, everything seemed fine, I logged in, and the screen was all sorts of colors and lines. After I clicked, it showed just the background. I summoned up gnome-do, checked the additional drivers. The driver was not installed, and then the error report popped up. Gnome panel reopened fine with a terminal command. Going to try the FGLRX without the post release updates, it's always worked better for me.

Thanks for your time!
