Hello. I am still having this bug on 12.10 AMD64. That affects all the Gnome applications (gnome-something...).
Besides the fact that all or almost gnome apps lost their integration with Ubuntu Global Menu, I get the same error. Example: in Terminal, run : zenity --progress This problem occured when I used the GNOME3 PPA to upgrade NAUTILUS . When I purged this latter and re-updated, the issue still presists. AM I missing something? Or the fix was only for RR. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk3-engines-unico in Ubuntu. https://bugs.launchpad.net/bugs/1077568 Title: Theme parsing error: gtk-widgets.css:62:17: Theming engine 'unico' not found Status in “gtk3-engines-unico” package in Ubuntu: Fix Released Bug description: Get many : " Theming engine 'unico' not found " error logged by different packages (gnome and the likes, apport) Looking at libgtk-3-0 dependencies, there is : "Breaks: gtk3-engines-unico (<1.0.2-0ubuntu2)" And RR actually have version "1.0.2+r139-0ubuntu2" which seems to confuse libgtk-3-0, and producing that error.
