Problem with GStreamer on specific machine [NETWORK STREAM]

[Chuck Crisler]

The curious thing is that your server captures 1280 x 800 but this client
claims 640x480. If the client allocates a receive buffer for 640 x 480 it
will be over-run and who knows what will happen (probably bad). My guess is
that the reported error, while real, isn't the initial problem. It may not
be able to read because the application is crashing. Compare this log with
a log from a working client to see if you can spot some difference in the
receive setup. Also, verify that you have the same versions installed on
all systems.
