What version is your svn client, and what version is your svnlook?

There were some "recent" fixes in the diff code [1]. These fixes were
part of 1.8.0 (and backported to the latest 1.7.x releases). So if
your svnlook is a bit older, you might still be hit by these bugs.

[1] Fixes in the diff code, included in 1.8.0:
http://subversion.tigris.org/issues/show_bug.cgi?id=4283 (When the
identical suffix starts at chunk boundary, "svn diff" produces
incorrect diff)
http://subversion.tigris.org/issues/show_bug.cgi?id=4270 (diff -cN
shows wrong line changed)
http://subversion.tigris.org/issues/show_bug.cgi?id=4133 ("diff -x -w"
showing wrong change)
http://subversion.tigris.org/issues/show_bug.cgi?id=4339 (diff suffix
scanning invalid read at chunk boundary)
