gnome-panel crashed with SIGABRT in __kernel_vsyscall()

[Eliah Kagan]

On an Oneiric i386 system with ubuntu-desktop 1.245, lubuntu-desktop 0.28, xubuntu-desktop 2.138, gnome-session-fallback 3.2.0-0ubuntu3 (but no gnome-shell), and gnome-panel 1:3.2.0-0ubuntu1, on which the last graphical login had been a Lubuntu Desktop session, I logged in with a GNOME Classic session, then logged out and logged in with a GNOME Classic (no effects) session. No crashes occurred. Then I rebooted and logged in with an Xubuntu session, and was informed that gnome-panel had crashed. I found this strange, since Xfce does not use gnome-panel, but perhaps the crash was from the previous login.

The stack trace is very bad, and I suspect this bug report will be worthless, but I'm submitting it in case it's not. This resembles bug 759451 and bug 850113; perhaps it is one of them.

Thank you for your report!
