script error at differences list

What steps will reproduce the problem?
1. clean instal of Joomla 1.5.15 (domain.com/copy) & installing working copy
2. copy site with WC to ../paste
3. click differences button in child (/paste)

What is the expected output? What do you see instead?
I don't get a list of differences but an error:
