Public bug reported:
I tried running the Ren'Py game "Analogue - A Hate Story" (the Steam version in
my case) with the renpy build from Ubuntu 12.10 (6.13.12-1build1).
After the intro, the game does not switch over to the main menu, but crashes in
rw_close_th.
I couldn't find debug symbols for the the python-renpy package, so I
apt-get source'd renpy and disabled the dh_strip stage, then built and
reinstalled it. A resulting gdb stack trace is attached.
As I don't understand Python/C very well, I just took a wild guess at
why the crash is happening. Based on the assumption that
PyObject_GetAttrString does not increase the reference count, I added
Py_INCREF() calls to fetch_object_methods(). If this is incorrect, I can
see another bug here: if the PyCallable_Check() call returns false, the
references are never decremented. With the reference count increase, the
crash vanishes, but I can't tell if this instead creates a memory leak.
It would be great if a Python guru could provide some insight.
Upstream versions were not tested.
