The bell just have rung. I got exactly that in my .emacs:

(setq org-caldav-exclude-tags '(ARCHIVE))

after changing it to:

(setq org-caldav-exclude-tags '("ARCHIVE"))

the syncing works again. I just cannot understand why it was working
before. And sorry for bothering you with that backtrace file. The issue
is solved.

Thank you a lot.
