When the BTS catches up it will contain this information:

   The file system is ext3 with 2.6 kernel.  

   [11:03][arafune1:/export/SVN_common/hooks]$ ls -f -1

I asked the bug reporter to run "ls -f" which returns unsorted
entries, you can clearly see that "." and ".." do not come first.

Thanks, that will solve our problem long term.  I wonder what we
should do for Subversion 1.0?  Ship with a big disclaimer that hotcopy
does not work on ext3?  Implement our own dot-first stuff in
svn_io_dir_walk?  Wait for an APR fix and require that version?  I've
had a look at the Subversion code and I think hotcopy is the only
thing affected.
