After using the GNOME3 PPA to upgrade Nautilus , (I have been working with it for several days without problems), the Global Menu broke for all Gnome-application, like
nautilus 3.4, etc...).
At the same time, when I launch any of these applications from terminal, I get the following error:
Gtk-WARNING **: Theme parsing error: gtk-widgets.css:62:17: Theming engine 'unico' not found
I purged the GNOME3 PPA, re-updated, auto-cleaned, dist-upgraded, downgraded Nautilus, reinstalled the
appmenu, but in vain.
Anyone has a clue of fixing this?
~$ apt-cache policy gtk3-engines-unico gtk3-engines-unico: Installed: 1.0.2+r139-0ubuntu2 Candidate: 1.0.2+r139-0ubuntu2 Version table: *** 1.0.2+r139-0ubuntu2 0 500 http://archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status ~$ apt-show-versions gtk3-engines-unico gtk3-engines-unico/quantal uptodate 1.0.2+r139-0ubuntu2
The Unico issue seems to be known in RR.13.04.
I have Installed gtk3-engines-unico from RR-13.04, to see if it fixes the issue but in vain. Now I get a different error message when running a Gnome application from Terminal:
Failed to load type module: (null) menu_proxy_module_load': /usr/bin/python: undefined symbol: menu_proxy_module_load
But what about 12.10?
