It looks like you were selecting a menu item. The stack trace says that it crashed in a native shared library: libgobject-2.0.so.0
I don't know what that library is, but maybe there's a bug in it. Are you really opening 70 windows at once inside Eclipse? Why so many windows; is it really necessary? Maybe you're hitting a limitation somewhere.
