           Summary: Assertion failure in DocumentLoader::commitData when
                    loading a media document in WebKit2
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: NeedsRadar
          Severity: Normal
          Priority: P2
         Component: Page Loading

This is the WebKit2 equivalent of bug 48531.


To reproduce:

1. Go to http://www.nch.com.au/acm/sample.wav in a debug build

You'll hit an assertion in DocumentLoader::commitData:

    ASSERT(m_frame->document()->parsing());

The wav file seems to load fine in Release builds.

Here's the backtrace:

Note that on Mac you'll instead hit a crash (bug 48559), but if that crash didn't happen this would.
