weird mneisa/escript problem in r13

i am using mnesia from within some escript code, and i cannot get
it to work on both r13b01 and r13b02-2.  the error occurs when i call
mnesia:create_schema( [Node] ).  i specify an mnesia dir on line 2 of
the escript code using one of:

1) %%! -mnesia dir '"test/bunderl"'
2) %%! -mneisa dir "test/bunderl"

when i use version 1, it works on r13b01, but fails on r13b02-2 with:
{"Cannot create Mnesia dir",
"/home/garry/admin/\"test/bunderl\"", enoent}}
and yes, the appropriate dirs exist, and it fails the same if i clean
it out between runs.  i am running it from /home/garry/admin, and 
test/bundle exists and is writable and all that.

when i use version 2, it works on r13b02-2, but fails on r13b01 with:
=ERROR REPORT==== 2-Nov-2009::23:28:06 ===
application_controller: bad term: test/bunderl
escript: exception throw: {,
                      {application_load_error,
                          {bad_environment_value,"test/bunderl"}}}

am i doing something wrong, or is there a bug in one or the other of 
these releases?
