segfault with Clone() called on GeometryRef of Feature

[steko]

originalFile = ogr.Open('data.shp')
memory = ogr.GetDriverByName('Memory')
workingFile = memory.CopyDataSource(originalFile,'TemporaryDS')
workingLayer = workingFile[0]
self.workingLayer.ResetReading()

# create a copy of this geometry
total_geometry = self.workingLayer.GetFeature(1).GetGeometryRef().Clone()

The last line will result in a segfault, even though feature 1 exists and has a Geometry. This

total_geometry = self.workingLayer.GetFeature(1).GetGeometryRef()

works without any problem. This can probably be solved not using a oneliner.

This is definitely a variable scoping issue. I would call it a bug, but it isn't going to be fixed any time soon. Please use more verbose method calls to ensure intermediate variables do not go out of scope.
