gdb in Ubuntu links against libpython3.4.

The Python scripts in /usr/share/glib-2.0/gdb haven't been fully ported
to Python 3: the custom iterators should define a '__next__' method
alias pointing to 'next'.

** Also affects: glib2.0 (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: gdb (Ubuntu)
       Status: New => Invalid

  Python Exception <class 'TypeError'> iter() returned non-iterator of
  type '_iterator'

  Invalid
Status in glib2.0 package in Ubuntu:
  New

Bug description:
  I tried to gdb a gnome-shell segfault:

  (gdb) bt
  #0  0x00007f8cad51f638 in g_slice_alloc (magazine_chunks=0xf879b0) at /build/buildd/glib2.0-2.44.0/./glib/gslice.c:535

  Python Exception <class 'TypeError'> iter() returned non-iterator of type '_iterator': 

  This looks like a bug in a gdb pretty-printer that's shipped with
  Ubuntu.
