Hello,

I had the same problem,
Apache master and mirrors are at dav_svn version 1.5.0,
I just upgraded my local client to svn 1.5.1 and had the same effect:

commiting of changes did work, adding failed with a 400 Bad Request message.
After downgrading the local client to svn 1.5.0 everything worked fine
again.
So it seems to be an issue in the 1.5.1 client.

regards,

Matthias
