The following script is what I used to convert a simple svn repository. It doesn't handle branches or tags and contains buggy use of grep and inscrutable uncommented use of sed but it should be a starting place for someone with a more complex repository available for testing.

export GIT_AUTHOR_EMAIL=sk@sethwklein.net
export GIT_COMMITTER_EMAIL=sk@sethwklein.net
svn co -r 1 file:///home/sk/rep/oakheart/trunk oakheart
cd oakheart
git-init-db
for REV in `seq 2 692`; do
    echo -n $REV' '
    svn update -r $REV > .svnupdate
    sed -nr 's/^A +//p' .svnupdate \
    | while read F; do [ -f "$F" ] && echo "$F"; done \
    | xargs -r git-update-cache --add --
    sed -nr 's/^D +//p' .svnupdate \ 
    | while read F; do git-ls-files | grep "^$F"'\(/\|$\)'; done \
    | xargs -r git-update-cache --remove --
    sed -nr 's/^U +//p' .svnupdate \
    | while read F; do [ -f "$F" ] && echo "$F"; done \
    | xargs -r git-update-cache --
    PARENT=
    [ -f .git/HEAD ] &&
        PARENT='-p '`cat .git/HEAD`
    svn log -r $REV | sed -n '1,3d;$d;H;/^$/!{s/.*//;x;s/\n//;p}' \
    | git-commit-tree `git-write-tree` $PARENT > .git/HEAD
done

Cheers, Seth W. Klein
