Lacking any understanding of how this can happen, we do this check here to avoid crashing. 619720 6 webkit.review.bot 2012-05-09 12:11:42 -0700 Attachment 140992 did not pass style-queue: Failed to run "['Tools/Scripts/check-webkit-style', '--diff-files', u'Source/WebKit/chromium/ChangeLog', u'Sourc..." exit_code: 1 Source/WebKit/chromium/src/FrameLoaderClientImpl.cpp:642: Use 0 or null instead of NULL (even in *comments*).
