Bug Description

The following example code gets the nux rendering into an infinite loop where we don't get any rendering.
(remeber that atm nux::StaticCairoText is in lp:unity)

nux::VLayout* title_data_layout = new nux::VLayout();

nux::ObjectPtr<nux::StaticText> title_;
title_ = new nux::StaticCairoText("", true)

title_data_layout->AddView(title_.GetPointer(), 1);


If the above code does not set the maximum width of the text or we use the StaticText everything works as expected.
