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

[Fabien Tassin (fta)]

Many dupes:
- all 32bit
- many using the nvidia-current driver
- many claiming it crashed after an upgrade / unrelated pkg install.

Same for me. I've cornered it a while ago to gtk-update-icon-cache, which is triggered by the dpkg "triggers".

I can reproduce easily:
1/ sudo gtk-update-icon-cache --force --quiet /usr/share/icons/hicolor
2/ go the Activities Overview (the Dash) by moving the mouse to the top left corner
=> boom

Fixed & verified upstream in trunk.
Someone may have to backport the 2 commits fixing this (00091a2 & 0a7968a)

This bug was fixed in the package gnome-shell - 3.4.1-0ubuntu2
