It is too late now. I have seen it :-)

It is indeed a Lazy-shot bug. It is fixed in 21.0. Gnus is probably
copying parts of the buffer around into strings and lazy-shot does not
like that very much. However this is also a good indication Gnus is
using buffer-substring somewhere where it probably needs
buffer-substring-noproperties.
