[maemo-developers] [maemo-developers] Is this a bug in python-osso ? (osso rpc call with argument)

[From: Pierre Amadio]

Hi there.

As a followup of my previous message (problem using dbus rpc call with
argument in python) i decided to give rpc_async_run a try instead of
rpc_run.

Now, not only it 'does not work', but pyhton2.5 segfault as well.

I guess i did something wrong like not having an osso context properly
set or something like this, but i also feel it should be up to libosso
or python-osso to check the argument it use ar ok, shouldnt it ?

I have attached a test cased based on :
http://maemo.org/platform/docs/python-bora/python_maemo_howto.html#Introduction+to+LibOSSO

I also try to catch a backtrace, with 'gdb /usr/bin/python2.5  core' ,
but i m not that familiar with gdb, nor do i know where to get the
python-osso debug symbols.

Anyway, the begining of the backtrace looks like this:
#0  0xb72d068c in _python_to_rpc_t () from /usr/lib/python2.5/site-packages/osso/rpc.so
#1  0xb72cfc61 in Context_rpc_run_with_defaults () from /usr/lib/python2.5/site-packages/osso/rpc.so
#2  0xb79f09b9 in osso_rpc_run () from /usr/lib/libosso.so.1

Am i wrong in thinking there is something wrong in python-osso ?
I use python2.5-osso 0.2-1osso1.

_python_to_rpc_t is defined in python-osso/src/osso-helper.c, but this
is where i m stuck at, not understanding what may be wrong there (i
guess one of the 2 argument being sent has not the right type or size or
something, but that s about it).

Any help would be appreciated.
