Hi Sebastian, this is not really an issue for debugging.
The list parser used by the LaTeX exporter simply does
not cater for text intermittent in a list, and the Lisp structure
created by the parser does not have a way to represent
such text.  So this is not "a bug" you'd have to find, but rather
new code which would have to be written.....

yes, or (debug)
