I keep hitting this assert on Windows when dragging around the map on
weather.com (see URL).  It doesn't happen immediately, but if you zoom in/out
and drag around for a bit you'll hit it.

I also get a number of these messages printed to the console before this
assert:
pluginstreamwin.cpp(282) : WebCore::PluginStreamWin::deliverData: Stream failed
due to problems with network, disk I/O, lack of memory, or other problems.
pluginstreamwin.cpp(363) : WebCore::PluginStreamWin::didFail: Stream failed due
to problems with network, disk I/O, lack of memory, or other problems.

(FWIW, none of the other machines on my network have any issues, nor do I have
any disk I/O or ram issues).
