Comment 2 for bug 292622

I experienced the same bug. I found the problem because tasque couldn't connect to the evolution dataserver, too. Tasque said a dll was missing. The problem is that
/usr/lib/libedataserver-1.2.so.9 does not exist as softlink in intrepid.

The a quick fix for tasque and for gnome-do is to execute the following command:
sudo ln -s /usr/lib/libedataserver-1.2.so.11.0.0 /usr/lib/libedataserver-1.2.so.9

(this assumes that libedataserver1.2-11 is installed)
