I could reproduce and fix this problem. However, I would have been glad if you 
had told me sooner about this problem, i.e. right after you discovered it in 
the 20040821 snapshot.

That is correct. With the later snapshot I introduced XML validation and the 
respective DTDs. Therefore the project files are not backward compatible if 
you are using a validating parser (what happend here, s. traceback). However, 
the newer eric versions are still able to read the older project files.
