[Pkg-roundcube-maintainers] Bug#989140: roundcube-core: Error displayed during upgrade if manually installed plugins are in use in /var/lib/roundcube

[Kurt Fitzner]

Package: roundcube
Version: 1.4.11+dfsg.1-4
Severity: minor

During an upgrade of roundcube-core, if there are any manually installed
plugins in /var, then an error is shown:

Setting up roundcube-mysql (1.4.11+dfsg.1-4) ...
Setting up libx11-xcb1:amd64 (2:1.7.1-1) ...

Something is either looking at the roundcube configuration, or iterating
through all the plugins in /var/lib/roundcube/plugins and wanting to
associate them with the package-supplied plugins which are in
/usr/lib/roundcube/plugins.  However, only plugins supplied by the package
/should rightfully exist in /usr/lib/roundcube/plugins.

The script can assume that all plugins in /usr/lib/roundcube/plugins/* exist
as a link to /var/lib/roundcube/plugins/*, but the reverse cannot be
assumed.

Why the upgrade script for roundcube-core was looking at the plugins, and
why it made the assumption that the /var plugins must also all exist in /usr
is unknown.  It may be a disply-only error with no actual ramifications. 
That being said, the assumption of a reverse correlation shouldn't be made.
