error output

Build ID: M20060629-1905

Steps To Reproduce:
1.After closing and reopening different projects, the ant buildfile automatically closes with the project. So you have to re-add it to the ant window.
2.Add a buildfile to ant via drag & drop or the add button
3.'an error has occured' message from eclipse right after adding the buildfile. It does NOT get parsed and ant does not work afterwards. eclipse has to be restarted.

This does not occur EVERY time I try to add the buildfile. Only after closing & reopening a project X times (different every time, and all build files sometimes refuse to be parsed, it's not file-specific - the XML is correct and it does get parsed most of the time).
