I expected a regular closing of a window that was embedded in the gnome bar

After sliding erratically about using Ctrl-Shift-Arrowkeys I went to close a terminal window at which point the compiz segfaulted and reset twice.

Thanks for the bug report. Can you please install the debug symbols of unity, compiz and nux and then try to obtain a backtrace by following the instructions here <https://wiki.ubuntu.com/Unity/FilingBugs#Getting a stack trace> and attach to this bug report.

[Tom Bell (bushbaby2511)]

I can't seem to reproduce the bug for the logs.

Current Unity version is 3.6.8-0ubuntu3
Current compiz version is 1:0.9.4git20110322-0ubuntu5

Since the bug report several compiz packages have been updated with no change to the version number

compiz
compizconfig-backend-gconf
compiz-core
compiz-fusion-plugins-main
compiz-gnome
compiz-plugins
compiz-plugins-main

With several unity updates and gnome package updates some of which are listed

unity
unity-asset-pool
unity-common
unity-place-applications
unity-place-files
ubuntu-desktop
ubuntu-docs
ubuntu-minimal
ubuntu-mono
ubuntuone-client
ubuntuone-client-gnome
ubuntuone-control-panel
ubuntuone-control-panel-gtk
ubuntu-sounds
ubuntu-sso-client
ubuntu-standard
ubuntu-system-service
ubuntu-wallpapers
gnome-desktop-data

I don't know if this helps but I'll assume It has been fixed in the interim given the lack of reproducibility?
