Package: yasnippet Version: 0.11.0-2 and 0.12.2-1 On creating a no-change backport package (→ ppa:dirk-computer42/c42-backport) i found the following transistion problem.
yasnippet 0.9 contains the file /etc/emacs/site-start.d/50yasnippet.el On upgrade this isn't removed until the now transitional package yasnippet is purged. So after `apt-get dist-upgrade` it is still existing and lead to the following error message: > Error while loading 50yasnippet: Symbol's function definition is void: yas--initialize My advice is to ensure explicit removal of this outdated file.
