Steps to repro:
- create a File object (via <input type=file> etc)
- delete a File
- create a Blob including the file
- read the Blob

The bug is introduced by http://src.chromium.org/viewvc/chrome?view=rev&revision=138702
but is also partly due to WebCore's current implementation.

This can be tested with following tests (bug 87356) [you'll need to remove chrome-specific rebaseline results]:

fast/files/read-blob-async.html
fast/files/workers/worker-read-blob-async.html
fast/files/workers/worker-read-blob-sync.html
