The failure occurs at line 8 of src/_gtkagg.cpp; there is no
matplotlib code on line 8 or above, so I do not believe it is a
matplotlib problem.  I think it is either a pygtk problem or a problem
with your environment (does your pkg-config point to the proper pygtk
install path?).  Below is a c++ file that is identical to _gtkagg.cpp
up to the failing line, which is the gobject import.  After that it
just prints hello world.

Try compiling it with (where the python include path should point to
Python.h)

  > g++ test.cpp `pkg-con-2.0` -I/usr/local/include/python2.3/

Are you using gcc-3.4?  This seems to be a specific problem with
gcc-3.4 and pygtk-2.4.  It would be helpful if you post your gcc
version, platform and pygtk version.

Please let me know if you learn anything else.  If you fail to compile
the minimal example below, check your pygtk pkg-config paths and
consider posting this example to the pygtk mailing list; Niklas posted
and got no response, but he didn't have a minimal example which will
make a world of difference in people's ability to help.
Unfortunately, I don't have access to a machine with gcc-3.4 and the
latest pygtk to test with.

//test.cpp
#include <cstring>
#include <cerrno>
#include <cstdio>
#include <iostream>
#include <cmath>
#include <utility>

#include <pygobject.h>

int main() {
  std::cout << "hello gtk" << std::cout;
}
