How to reproduce on Utopic: 1. sudo apt-get install Numix 2. sudo apt-get install gnome-tweak-tool 3. change Gtk theme to Numix 4. Open any app with Gtk-Headerbar (& NOT directly patched by Ubuntu) like gnome-tweak-tool, gnome-system-log 2. enable show-desktop on unity launcher 3. Click on show-desktop first time. it will show desktop. 4. Click on it again, it crashes compiz & sometimes does not recover from it. Users have to fallback to TTY & force restart lightdm. The problem also occurs for any headerbar app from Gnom3 ppa (for example gnome-contacts, baobab, gnome-maps). Attached crash file from /var/crash/compiz. Note: Compiz on other desktop shell/session works relatively well. For example in Gnome-Flashback-Compiz session it doesn't happen.
