The error is saying it can't open the file, not that it has problems with the contents. Make sure the name/location of the xml file matches the entry on the .toc. In live the entry would just be ignored if the file didn't exist.

It also appears that you have a reference for the file in 4 different places which is odd so, maybe there are old associated addons that have this file listed in their .toc as well.
