PyGILState_Ensure assertion failed - OLPC - XO

[Pablo Posada <pablo posada tcs com>]

Hi,

The project goal is to incorporate the
functionality of interaction of the excel application (gnumeric) with the
XO's journal. All the activities needs to register any change in that datastore
(save and open files are made throw it). 

In order to apply this option, we need
to call some python code from the implementation of the worksheet in C
code. This is called embedded python in C. The steps followed to accomplish
this goal came from the OLPC site recomendations, in wiki.laptop.org. The
python script for the interaction with the journal's datastore we get from:
http://wiki.laptop.org/go/Copy_to_and_from_the_Journal

The changes in the gnumeric code are
basically in the workbook-view.c and main-application.c to handle the open
and save options. In the main-application.c the method gui_file_copy_from_journal
uses the python api/c to make the call to the journal script. after this
method and during the open of the file, an exception rises. Although we
are not sure, we believe it has to do with the closure of the python enviroment
after the finalize call. We need to erase this exception or may be just
handle it. 

The error running in the XO is: 

gnumeric: Python/pystate.c:561 :
PyGILState: The assertion 'autoInterpreterState' has failed 

The configuration of the XO where we
are getting the exception is: 

Python 2.5 (r25:51908, Oct 19 2007,
09:47:40) [gcc 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2 

The error is only rised if the python
code calls the datastore's functions.

Does anyone have integrated a C application
with the journal functionality? And solved this issue?

Thanks you all,
