git svn exits with error error closing pipe: Bad file descriptor

After upgrade to subversion 1.8.0 on some repositories
git svn clone shows two warnings:

error closing pipe: Bad file descriptor at
/home/users/kornet/giti/libexec/git-core/git-svn line 0.

at exit. They appear because process git cat-file --batch exits before
command_close_bidi_pipe is called by destructor during perl exit.  The
solution is to call the destructor explicitly, e.q.:

index ff1ce3d..6811738 100755

 Data structures:

However I'm not sure whether it is not a symptom of some other error.
What's confuses me more is that the warnings don't appear for all
repositories. For example they appear for  http://svn.pld-linux.org/svn/cdpl/
while cloning http://svn.pld-linux.org/svn/atob ends normally.
On the other hand it is consistent between two different machines with
different Linux distributions and perl versions.
