shiboken.dump segfaults when called on deleted object

The following code leads to segfault:

from PySide.QtCore import QObject
import shiboken

o = QObject()
shiboken.delete(o)
shiboken.dump(o)

The root cause is std::string info(SbkObject* self) in libshiboken/basewrapper.cpp does not check to see if self->d->cptr is NULL before indexing it as an array.
