          Platform: Macintosh Intel

This just happened twice in a row; I'm not sure what's causing it, but here's the repro + stack in the client I used.
I see nothing odd in the ChangeLog that it should be modifying.

[WebKit] gvim WebKit/chromium/src/AsyncFileWriterChromium.h
[WebKit] WebKitTools/Scripts/webkit-patch prepare
