[Qgis-developer] symbolForFeature(feat) causes minidump in converted 2.5d layers

[Matthias Kuhn]

Hi Tom,

Quote from the API docs:

> Must be called between startRender()
<http://qgis.org/api/classQgsFeatureRendererV2.html#ab4513895a219eb24e803fe9de34c230b> and stopRender()
<http://qgis.org/api/classQgsFeatureRendererV2.html#a704fb69e3906576444b87e28084d2235> calls.

Cheers
Matthias
