[PyQt] QPainter warnings when resizing a QWebView element

I'm attempting to use flot, a jquery/javascript plotting library to draw
plots in a QWebView.  Everything goes well except that I need to resize the
plot as the window resizes.  I'm doing this in Javascript, of course.  Once
the resize occurs and my redraw callback fires, I get a warning over and

QPainter::end: Painter ended with 2 saved states

A short program program to reproduce the issue is here:

When I comment out the redrawing javascript code, which is using the canvas
tag, the warnings disappear.  I suspect it's something with the canvas

Is that warning something to be concerned about?
