Almost everything doesn't work

[Giacomo]

I have installed twice Gnome-DO 0.9 from ppa in Xubutnu (Ubuntu 14.04.1 LTS) I am expiring the following issues:

>calculator doesn't work but at least doesn't crash

>DO crash when i try to perform a web search using web search plugin what does it say in the terminal:

Cairo.Surface is leaking, programmer is missing a call to Dispose
Set MONO_CAIRO_DEBUG_DISPOSE to track allocation traces

(Do:5883): GLib-CRITICAL **: Source ID 86 was not found when attempting to remove it
and I have to restart it again

>Even most of the desktop functionality (like tile windows etc. etc.) don't work.

I think that is not a matter of plugin but of Gnome-do for this reason I post it here. Thanks a lot for you help!
