Inserting a todo with menu or shortcut crashes XCode

[Bengreen]

I am using Xcode 5.1 and trying out XToDo.
i have latest pull from git.
i built it in Xcode, then closed xcode.

i opened up Xcode and opened the XToDo project and tried to insert a todo. This worked perfectly.
i then moved to another project (which is C++ based) and tried to do an insert of a todo using both the menu and the shortcut. ( i have only tried doing todo). When i do this it crashes Xcode every time.
The project in question has only got one file main.cpp (i.e. it is the basic project when you create a new C++ project).

Are there any traces i can switch on to help debug and provide better feedback here?

maybe the native Console.app logs what happened?
