 Hi, r15306 crashes with a bad allocation message when zooming on a
 specific layer in a specific project.


 It happens on one sqlite vector layer (town's borders) and any layers
 created from it with the 'save selection', if I open these layers in a new
 project there is no problems but if I delete them and add them back in the
 original project, then it crash again.


 Changing the symbology doesn't solve it, even with the default style.


 Here is how to reproduce the bug :
 1. open the project "badallocation_testcase.qgs"
 2. place the view on a polygon and zoom up to 1:606

 Here is the last messages before the error window (DebugView) ->
