coreutils cp won't work

[GoogleCodeExporter]

When i try to copy a file to a tahoe-lafs-mounted directory, i get the 
following:

cp: cannot create regular file 'test': No such file or directory

The strace exerpt:

open("test", O_WRONLY|O_CREAT|O_EXCL, 0644) = -1 ENOENT (No such file or 
directory)

Though dd works (and triggers the 
https://code.google.com/p/pyfilesystem/issues/detail?id=186 bug if used w/o the 
workaround):

open("test", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 EFAULT (Bad address)
