[C++-sig] Crash (segfault) on del(x.__dict__) where x is a boost.python wrapped instance.

[Alex Mohr]

Tested with boost 1.34 on x86-64 linux, gcc 4.1.2.  I have attached a 
very small example below.

I know that del(x.__dict__) is a rather odd thing to try to do, and we 
stumbled upon this by accident.  It is not a big deal for us.  That 
said, it might be nice to fix if it's easy.

Thanks,

Alex
