Dynamically switching themes crashes the widgetset in Chrome

[coshxx]

We are using UI.getCurrent().setTheme() to dynamically switch themes on application startup.

Now, when we have a chart on the first page and use setTheme() to switch to a different theme, the widgetset bugs out with:

SEVERE: (TypeError) : Cannot read property 'removeAttribute' of undefined
com.google.gwt.core.client.JavaScriptException: (TypeError) : Cannot read property 'removeAttribute' of undefined
at Unknown.Chart.destroy(Unknown)

After this crash no xhr requests will be sent by the widgetset anymore and in turn the listeners (ChartSelectionListener for example) won't work any longer.

This happens using Vaadin7, Vaadin8 and Charts v3 and Charts v4.

Only Chrome seems to be affected. In FF or IE the widgetset doesn't bug out.
