I'm sorry, but the crash report is long gone. It was in /var/crash/ -- I can only assume that it was cleaned up during reboot or by a cron job.
Maybe the package manager did something to cause the crash, or it could have been just random coincidence -- either way, I have only seen it once and have no way to reliably reproduce it. Next time I see a crash, I'll follow the instructions on the page you mentioned. I have the standard Flash and Java installed via the package manager: Shockwave Flash 9.0 r31 Java(TM) Plug-in 1.5.0_08-b03 And these extensions: Adblock 0.5.3.043 Diggler 0.92 Live HTTP Headers 0.13.1 Mouse Gestures 1.5.2 Stop-or-Reload button 0.2.2 -- firefox crashed while update-manager was running https://launchpad.net/bugs/81863 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
