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. ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Tags: utopic ** Attachment added: "/var/crash/_usr_bin_compiz.1000" https://bugs.launchpad.net/bugs/1387163/+attachment/4248133/+files/_usr_bin_compiz.1000.crash ** Summary changed: - 'Show Desktop' on launcher crashes compiz for any Gtk-Headerbar app when using any third party Gtk(3.12) theme (Utopic/Vivid) + 'Show Desktop' on launcher crashes compiz for any Gtk-Headerbar app when using any third party Gtk(3.12) theme (Utopic) ** Description changed: This is happening for any gtk-3.12 theme which has proper support for gtk-headerbar.
