error (bad message) when committing

[Matt Funk]

Hi,

i am using bazaar on a windows to windows system as a checkout.
I installed a freesshd server on windows system 1 and checked out and
developed on windows system 2.
Now i would like to commit the changes back to windows system 1.

I do: bzr commit -m "my message" -Derror
i get a prompt from the ssh server and type my password. After that bzr
gives me the following:

Authentication (password) successful!
Secsh channel 1 opened.
[chan 1] Opened sftp connection (server version 3)
bzr: ERROR: exceptions.IOError: Bad message

Traceback (most recent call last):

Does anyone know what is going on? Is this a user error?
Any help would be appreciated.

thanks
