########### THINGS THAT HAVE FAILED DURING HAND-TESTING ##############
#
# These have all been fixed, but we want regression tests for them.
#
#   1. Ben encountered this:
#      Create a greek tree, commit a keyword into one file,
#      then commit a keyword property (i.e., turn on keywords), then
#      try to check out head somewhere else.  See seg fault.
#    
#   2. Mike encountered this:
#      Add the keyword property to a file, svn revert the file, see
#      error.
#
#   3. Another one from Ben:
#      Keywords not expanded on checkout.
