[pygtk] Can't run PyGTK more than once from embedded Python

[Romain Behar]

Thanks for all your answers, even if they're bad news.

I'll like to try this one, as the two other as
impractical (rewritting the application in Python, or
having a single interpreter).

Why running the script using:

 PyRun_String(my_script, 0, 0, 0);

or:

 PyObject* main_module =
PyImport_AddModule("__main__");
 PyObject* main_dict = PyModule_GetDict(main_module);
 PyRun_String(my_script, 0, main_dict, main_dict);

does nothing? The script runs  and ends, but printed
messages don't show in the console and PyGTK windows
don't open. Is that what you call "using different
namespaces"?

If it does not work, the only solution will be to
patch PyGTK to behave as all other Python modules...

Well, I'm in the worst case ;)
The application uses Python as scripting engine, it
imports the application's extension module. Anyone's
bound to write Python scripts to extend the
application!
