If the pipeline setup fails at the first widget/pipeline then we will have no spipe stored under the pipeline_list->pipelines, the pipeline_list->count is 0.
If this is the case we would have a NULL pointer dereference if the execution is allowed to proceed.
Check for this condition along with the pipeline_list->pipelines check
