Does this happen with a later version of Midori from the PPA?

J, please excuse the delay, we don't have fulltime developers. If somebody has time they go on a bug triaging round, fix pages, do testing or whatever else they can - if there's too many bugs and nobody does step up this is what happens.

To summarize the conditions, midori 0.5.0, Quantal, GTK+2, "midori -d", open http://www.google.com via the urlbar.
