I searched in the pino code source (when the timeline is update, the
scroll bar return at its old position) and the code is similar:
http://code.google.com/p/pino-twitter/source/browse/src/timeline_list_abstract.vala#89

But the scrollbar position is restored via callback. Is it necessary to
wait some time between the restoration of the contents of the liststore
and the position of the scroolbar?
