Chef Upgrade issue

Hello everyone.

We had chef-server v10.8.0 and decided to migrate to the latest one.
Migration was done following closely this article
http://www.opscode.com/blog/2013/03/12/5106/.
New chef server is up and running.

Everything is good except one problem:
chef-server now stores data which were in cookbook files like this:

123(it can be any random number)

^M
0^M
^M

And of course chef-client throws an exception.Here is a small stacktrace:

It complains on any file not just upstream.rb

Here is example file:
cat /var/chef/cache/cookbooks/uptodate/attributes/default.rb
60
default[:yum][:updates][:excludes] = [ ‘kernel’ ]

0

The question is how i can get rid of this strange symobls and numbers in
cookbook data after upload?I also tried upload cookbooks in an empty database
with knife cookbook upload cookbooks/.Result is the same.
