Actualy, I'm not sure that it's in gst-python or in gsreamer itself, but it only brakes python apps, and else because python is only one lang. which i know though somehow.
Comment 1 Zaheer Abbas Merali (RETIRED) gentoo-dev 2006-09-11 10:34:10 UTC 
Please can you re-emerge liboil.  This is the cause of the segfault in videotestsrc when importing gst in python.  liboil's ebuild now forces CFLAGS that liboil is compatible with.
Comment 2 Oleg S. Marin 2006-09-12 04:48:58 UTC 
Re-emerged liboil and even gstreamer and gst-python.
It did not help.
Comment 3 Samuli Suominen (RETIRED) gentoo-dev 2007-09-12 16:15:15 UTC 
OK, I haven't seen such behavior with dev-python/gst-python-0.10.8. This bug is now year old with no activity or duplicates. dev-libs/liboil has been bumped to 0.3.12, 22 June 2007.

Please try upgrading both liboil and gst-python and reopen if you still have this issue. Thanks.
Comment 4 Samuli Suominen (RETIRED) gentoo-dev 2007-09-12 16:17:16 UTC 
And do the actual testing without flags like -fforce-mem or -fforce-addr..
