Segfault in 1.6.4: svn_wc_remove_from_revision_control

Hello folks!

I encountered that nice baby today:

Program received signal SIGSEGV, Segmentation fault.
svn_wc_remove_from_revision_control (adm_access=0x96a2a98, name=0xb7f6c9cb "",

It appears in the context of a locked repository, when cleaning up
locks, and then removing an added but not yet committed directory.
(Mandriva 2009.1)

Is it something old/already fixed? I see a bunch of hits about issues
in 1.6.2, but I'm not sure about that one.

I was not able to backtrack enough to include steps to create a
locked/buggy repo, I'm attaching a small part of my repo, that
hopefully should be enough to reproduce the issue:

tar -xvzf segfault.tgz
cd foo/unit_definition_interaction_workflow
svn cleanup .
cd ..
svn cleanup .
svn rm --keep-local unit_definition_interaction_workflow # shabam

Please let me know if I can help more.
Please CC me as I'm not a subscriber here.

Thanks :)
