gephi-toolkit fails to open some gephi files

When the program reaches this line:

73   pc.openProject(file).run();

I get this exception.

org.gephi.project.io.GephiFormatException: Gephi failed importing the project.

The problem appears only on some files and it seems to corrupt the state of the application. Other files saved after closing those files copy the bug.

For example of files one could view this gist:
https://gist.github.com/adrian-castravete/6594428

Project.xml is the unzipped gephi file, before opening any other project in gephi.
ProjectBroken.xml is the unzipped gephi file, after copying the weird bug (after I opened a gephi file in gephi and closed it).

For some reason gephi isn't bothered by anything when opening and closing any of these files, but the gephi-toolkit fails after the bug has happened.
