Bad directories w/Reiserfs on linux-2.6.0-test4

Hello,
  This is about the third time I've seen this error on recent kernels:

  Sometimes my directories, say  dir/subdir, become dir//subdir.  This 
confuses many tools and I've even experienced some 'D' state processes trying 
to access such a directory.  My most recent problem is that even though 'ls -
l' shows dir/subdir ... 'rm -r' thinks it's dir//subdir and refuses to remove 
it.  Confusingly, however, 'mv' works and I can move the directory around.  
Also cd'ing into the directory is fine too.

$ ls -l
total 1
drwxr-xr-x    3 jesse    users          72 Sep 10 14:47 datatable-backup

$ cd datatable-backup; ls -l
total 1
drwxr-xr-x    2 jesse    users         256 Sep 10 15:10 CVS

$ rm -r datatable-backup/
rm: cannot remove directory `datatable-backup//CVS': Directory not empty


I've attached the strace file
