I didn't try reproducing the problem in a traceable local environment.
Instead, I've added code to ensure that the bobbfunc shared library is loaded before the action hooks for shutdown are assigned.
bobbfunc contains the kv() function that's used in bw_trace_trace_file_link() to set the link to target=_blank and some inline styling.
