nomachine NX: Text missing on all gtk interface (Unity and Gnome Classic)

I have found solution for identical problem in Arch forums.

You need to downgrade libcairo2 to 1.10 version (I have downloaded it from precise-updates repo - http://packages.ubuntu.com/precise-updates) and make order in resulting dependency mess.

I had to downgrade as well following packages: libcairo2:i386 (my system is amd64, but e.g. acroread depends on the 32-bit version of the library), libpoppler-glib8, and poppler-utils. The last two downgrades demanded installation of libpoppler19. All the poppler packages was taken from precise repos: http://packages.ubuntu.com/precise

Of course it is not a permanent solution, but everything works fine. I'm afraid we need to wait for some patch for the cairo library.
