This means a mutex is freed while it's still being locked. This could be
a bug in some plugin or piece of code, or it indicate a bug in the
application (might happen when there's a refcount error and an element
gets unrefed while still being used in the pipeline, for example).

Or an element/pipeline is unrefed/freed without having been set to
GST_STATE_NULL before.

What exactly does 'channel change' mean? How are you trying to achieve
this?
