I have a hover control using WMSGetFeatureInfo to return information about the features under the cursor which works in all situations except one.
I also have a LayerSwitcher control created with self.map.addControl(new OpenLayers.Control.LayerSwitcher());. When I hover over the +/- symbol used to open or close the layer switcher I get a javascript error. By adding breakpoints I know that the hover control's beforegetfeatureinfo event fires, but then not the getfeatureinfo or nogetfeatureinfo events.

According to Chrome Developer Console the error is
