What's the URL of the page containing the problem?
http://reviewboard.eng.vmware.com/r/681/diff
What is the expected output? What do you see instead?
The diff for the file strings_ja.js is wrong. There are a couple problems:
1) The one line that it claims has changed has not actually changed. You
can see the same line on both sides of the diff.
2) The diff of this file ends abruptly before the end of the file
3) The one line that has been added is not shown.
One interesting thing that I just noticed: It claims that a line has been
added at line 242, which is actually correct! The one line that was added
to the actual file is line 242, so maybe the diff viewer is what is not
working properly?
