Public bug reported:
This is happening for any gtk-3.12 theme which has proper support for
gtk-headerbar.
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.
