subversion 1.6.6 coredumping

Hi list.

I've just installed svn from ports on FreeBSD. It works for some
operations, but I get a coredump when running the following:

# svn export http://svn.facebook.com/svnroot/platform/clients/php/trunk
facebook-api
svn: In file 'subversion/libsvn_ra_serf/update.c' line 1620: internal
malfunction
Abort trap: 6 (core dumped)

Some background information:
# svn --version
svn, version 1.6.6 (r40053)
  compiled Jan 15 2010, 23:57:16

I compiled from official ports files.
