Hello NG, we are launching a python script which is accessing the gpgme libary for encryption/decryption : import os import gpgme from freeswitch import * ctx=gpgme.Context() ctx.get_key(’B9F2747A’) If we run this python script direcly in the command line (without "from freeswitch import *"), everything works fine. If we call the script within freeswitch using the mod_python module, we receive the following debug output, when the environment variable GPGME_DEBUG is set to „9:/tmp“: ... gpgme_op_keylist_start: enter: ctx=0x7fcd8c2078c0, pattern=B9F2747A, secret_only=0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_pipe: enter: filedes=0x7fcd8c1e5bc8, inherit_idx=1 (GPGME uses it for reading) GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_pipe: leave: read=0x1a5, write=0x1a6 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_set_close_notify: enter: fd=0x1a5, close_handler=0x7fcd84074420/0x7fcd8c1e5ba0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_set_close_notify: error: Invalid argument GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: enter: fd=0x1a5 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: leave: result=0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: enter: fd=0x1a6 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: leave: result=0 GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_op_keylist_start: error: General error <GPGME> GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_release: call: ctx=0x7fcd8c2078c0 GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_get_key: error: General error <GPGME> ...
