Bad Allocation when zooming

[jrm]

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) ->
