OOPS! Sorry. Trying to learn using debbugs.

I was just guessing about gnus-byte-compile causing problems. Reading the help
for debug-on-error I now think it is that the code is executed in a
condition-case that stops the backtrace from being created. Using
debug-on-signal does not seem to help in this respect either. (But I don't
know elisp good enough to tell.) Anyway the patch provided by Andreas seems to
do the trick.
