I get this bug on amd64 with an intel GPU, so it is probably not related to architecture or graphics driver.

I can confirm this bug on AMD64 with an ATI GPU (running fglrx drivers).

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please verify whether this bug still exists with the latest stable release: gnome-shell 3.2.1 in Ubuntu 11.10.

No longer is an issue here, will mark invalid

Appaport popped up when Gnome Shell crashed on me just now in 12.04 testing, updated to today's date.

Steps to reproduce: Running fglrx driver installed by jockey on a quad core xeon with VTX Radeon HD5450 graphics card. Load Firefox and scroll pages vigourously.

What I see: Screen freezes, then, after some seconds, alert reports that Gnome Shell crashed, top bar disappears and then reappears, appaport loads with a dump.

Affects me with Ubuntu 12.04 daily and Virtualbox guest additions 4.1.8

Affects me with Ubuntu 12.04 amd64, radeon hd 6850M fglrx, display is attached via hdmi

I started receiving this errors only after installing the latest driver from amd,
The performance of the driver is ok, no more corruptions or glitches on gnome and i can enjoy my video card.

I am running ubuntu 12.04 radeon hd 4330 on Dell inspiron 1545 and i am running gnome shell 3.2.2.1 so i don't think the bug is invalid.

The bug is the one described by keith burnett.

Thanks and please let me know if there is anymore info that i can possibly provide to help.

Happened to me on an old MacBook.

And too on a MacBookPro with ubuntu 12.04 - 32bits

Happened just now on a freshly upgraded Precise, EeePC 901 (32 bit, Intel graphics), gnome-shell 3.2.2.1-0ubuntu1.

This affects me as well, but on gnome-shell version 3.3.9 in Precise.

I am also affected on precise beta1. Similar bug reports are bug #949899 and bug #945349

Running ubuntu 12.04 with Ati Radeon video card.

Has been happening a lot since Precise beta-1.

It mostly seems to happen whenever a package that installed glib or dconf settings gets upgraded. Presumably, something in GNOME tries to run a massive update of gsettings via dpkg triggers at the end of the APT run and it crashes the currently running gnome-shell.

Happening to me on Gnome-Shell 3.4.

Just happened on 3.4/Precise beta 2 while running a dist-upgrade in a terminal. Shell froze, but the audio from an .avi in Totem continued (video was at the correct point when system resumed function).

I am trying to use Alt+Ctrl+T to open terminal.
It is defined in shortcuts.
I changed it to Ctrl+T and pressed it.
It opened new tab in running firefox instance.
And shell became irresponsible for couple of seconds.

Just happened on 3.4/Precise beta 2 while running a dist-upgrade in a terminal
