That sounds right. Unfortunately, I can reproduce it with
branches/1.7.x_at_1226297.

Some details:

The action is _add. The test script ran "svn update" after a
typechange (executable -> symlink) for a file named exec.sh. reason
is _replaced. The base status is _normal.

"svn log -v" reveals that /exec.sh is already present and already
known to be a symlink. However, the working copy is not up-to-date
--- the working copy of the file is still an executable.

Call chain:

    main -> svn_client_update4 -> svn_client__update_internal -> update_internal ->
     svn_wc_crawl_revisions -> svn_repos_finish_report -> finish_report ->
     reporter.c::drive -> delta_dirs -> update_entry ->
     update_editor.c::close_file -> check_tree_conflict

More precisely, this is the "local_is_link != incoming_is_link" case
in close_file().

In trunk after r1187692, it's gone. Instead of calling
check_tree_conflict(), that code path calls create_tree_conflict(),
avoiding trouble.

Thanks and hope that helps,
Jonathan
