Problem with 2.1 (4244) - svn: can't find a temporary directory

After upgrading from 2.0 to 2.1 (4244) projects stopped working, telling problems with
temporary directory. With 2.0 under the same environment it worked well.

We run TC under non-privileged account under Solaris 10, but this user has full r/w access
to common temp folders: /tmp , /var/tmp as well to own temp folders: ~/tmp , ~/temp

I suppose something changed in svnkit library, do we need to create an another temp folder, if so, which one ?

Thanks,
Dmitri
