Hi,all! I use gnus registry.el as follows ,------------------------------------------------------------ | ;;; Use the gnus registry | (require 'gnus-registry) | (gnus-registry-initialize) | (setq gnus-registry-install t | gnus-registry-track-extra '(sender subject recipient) | gnus-registry-max-pruned-entries 50000 | gnus-registry-max-entries 500000 | gnus-registry-split-strategy 'majority) `------------------------------------------------------------ before installing cedet 1.1. It always works fine. Since I have installed the cedet 1.1 by Gentoo portage, there is something wrong with gnus registry. When I start up the gnus by `m+x gnus`, emacs will complain and the report of bugtraces is attached in this message.
