Manipulating a cached WFS layer causes application crash

First I loaded a single WFS layer (from Geoserver) into QGIS 2.4 using the standard 'Add WFS layer' dialog, keeping the 'Cache features' option checked. Then in the Python console, typed the following code:

lyr = iface.legendInterface().layers()[0]

Then one of the following lines:

QgsMapLayerRegistry.instance().removeMapLayer(lyr.id()) # or:
lyr.reload() # or:
lyr.dataProvider().reloadData()

These cause a crash to desktop with no warnings, errors or dumps.

If I add a layer by unchecking the 'Cache features' option, none of the problems occur. I am also trying to add the the layer using pyqgis, and to work around this will probably have to insert a precalculated bbox parameter in the WFS url.
