In Chrome beta (currently 36.0.1985.49 beta-m) the WidthDetectorPanel runs into an Exception as it tries to parse an int but does not get an int.
This happens when you open the detail page of a node from grid when it tries to draw the overview graphs
This does work in the stable release of Google Chrome
