I've not used them myself, but git and hg have a bisect command for 
doing such searches.

There are tools that will produce git or hg repositories from a svn 
repository.

For copying a svn repository try:
   http://stackoverflow.com/questions/441297/copy-svn-repository
and also svnsync.

Here's the help for hg bisect.
===

$ hg help bisect
hg bisect [-gbsr] [-c CMD] [REV]

subdivision search of changesets

     This command helps to find changesets which introduce problems.
     To use, mark the earliest changeset you know exhibits the problem
     as bad, then mark the latest changeset which is free from the
     problem as good. Bisect will update your working directory to a
     revision for testing (unless the --noupdate option is specified).
     Once you have performed tests, mark the working directory as bad
     or good and bisect will either update to another candidate changeset
     or announce that it has found the bad revision.

     As a shortcut, you can also use the revision argument to mark a
     revision as good or bad without checking it out first.

     If you supply a command it will be used for automatic bisection. 
Its exit
     status will be used as flag to mark revision as bad or good. In 
case exit
     status is 0 the revision is marked as good, 125 - skipped, 127 
(command not
     found) - bisection will be aborted and any other status bigger than 
0 will
     mark revision as bad.

options:

  -r --reset     reset bisect state
  -g --good      mark changeset good
  -b --bad       mark changeset bad
  -s --skip      skip testing changeset
  -c --command   Use command to check changeset state
  -U --noupdate  do not update to target

Hope this helps.
