[Freeswitch-users] FS-6849: mod_python error everytime session is invoked for the first time right after a freeswitch start

[Nuno Reis]

Using gdb I've figured out that in mod_python.c:281:
...
result = PyEval_CallObjectWithKeywords(function, arg, (PyObject *) NULL);
Py_DECREF(function);
...

variable result is always null when a python script trying to use the
session run the first time right after freeswitch startup.
That will make it enter the else logic in line 291 in the same file ending
with a crash.
I'll still have to drill more to find out why this is happening now.
Anyone has a clue on what's going on?

BR,
