Comment #6 on issue 584924 by
bo...@chromium.org: K9 Mail fails to display
That CL exposed an existing bug I think..
If the base url is invalid, the load never goes into
RenderFrameImpl::LoadDataURL, since by that time, the base url has been
completely thrown out. It just tries to do a normal load of what's in the
url field, which after that CL, is simply an *empty* data url.
