It sounds like you're asking for an immediate workaround.  This would be
more appropriate for gnu.emacs.help.

Here on emacs-devel, I'd rather focus on fixing the problem, which
requires fixing the code that saves the registers, maybe making it
filter out those properties which contain unprintable values.
But apparently, this code is not in Emacs (nor (Non)GNU ELPA)?
