From the blogging this to remember next time department:

find src -type f \\
| grep -v svn \\
| while read f
do 
  echo "FILE:$f" 
  svn log -q
done \\
| egrep 'FILE|bob'

Additional svn log options like -r can be used to restrict the range.

Update: Julian mentions a way to avoid the grep, using find src -name .svn -prune -o -type f -print
