Status changed to 'Confirmed' because the bug affects multiple users.

[Ben Greear (greearb)]

I re-spun a 12.04 live-cd, and it happens on bootup (almos?) every time. Dmesg shows:

panel[foo]: segfault at c ip ....libindicator.so.7.0.0

Bug seemed to start happening after I did an apt-get dist-upgrade, as it worked fine
in an earlier 12.04 respin that I did.
