I will need to investigate this. Roundcube packages do not use Conflicts
(except for a real conflict with a previous version of
roundcube-plugins-extra but this is not something that was installed
here since it is not available in squeeze). There was no
renaming. However, roundcube-sqlite has disappeared and therefore
apt-get installs roundcube-mysql to satisfy the appropriate
dependency. I suppose this has something to do with the problem but I
don't know why exacly.
