I suspect that some handling of the HTML parsing might result in a NULL pointer dereference if some element is not found in the HTML or if the main.html file does not exist in the config dir.
I was able to reproduce the issue by simply renaming the main.html file (e.g. mv ~/.config/sov/html/main.html ~/.config/sov/html/main.html.bak). Then we see the following in sov's output to STDOUT/STDERR:
$ rm -f ${XDG_RUNTIME_DIR}/sovpipe && mkfifo ${XDG_RUNTIME_DIR}/sovpipe && tail -f ${XDG_RUNTIME_DIR}/sovpipe | sov -t 500 && rm -f ${XDG_RUNTIME_DIR}/sovpipe
