When receiving the error on the bus callback, print the debug part of the
error too, it is likely that it will help.

Also try running the application with GST_DEBUG=2 (at a minimum), to have a
little more information about the problem. If that doesn't solve, a full log
(GST_DEBUG=5) will lead you to the cause. Search for the error and go up on
the log until you find the reason for it to happen.
