Subversion Exception Report

Happened after update to new Tortoise version: TortoiseSVN-1.6.16.21511-x64-svn-1.6.17 --> TortoiseSVN-1.7.0.22068-x64-svn-1.7.0 (both .msi).

Happened while updating old (1.6) local repository to 1.7

Problem solved by saving content (files) of old directory structure by renaming it (directory), checking out originals from Server-Repository, and overwriting contents of checked out directory structure by saving files (by copy/paste, because it contains also unversioned files). One sub-directory remained inside after copy/paste with old format 1.6, but that could be converted without any further problems to 1.7 - maybe not the correct proceeding, but it worked. Do you have any other ideas/suggestions?
