Description follower 2007-04-11 13:14:42 UTC 
Steps to reproduce:
1. Switch to a non-X terminal (e.g. ctrl-alt-f1)
2. Execute: gst-launch-0.10 ximagesrc ! fakesink
3. A segfault occurs

Note: This is on an OLPC build 385 (on machine) and build 303 (in Qemu).

Running the above command in the Sugar developer console does not segfault.

I think this has already been fixed in gst-plugins-good CVS by this commit:

 2007-03-01  Zaheer Abbas Merali  <zaheerabbas at merali dot org>

        * sys/ximage/gstximagesrc.c: (gst_ximage_src_open_display):
        Error out correctly when getting xcontext fails.

Changeset:
http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/sys/ximage/gstximagesrc.c?r1=1.20&r2=1.21

Please re-open if you still have this issues with the patch applied.
