[Pkg-roundcube-maintainers] Bug#801973: error 255 on package configuration

[e-mmanuel]

Package: roundcube
Version: 1.1.2+dfsg.1-5
Severity: serious
Justification: 3

Dear Maintainer,

During upgrade of roundcube (from 1.1.2+dfsg.1-4 to 1.1.2+dfsg.1-5), 
aptitude reports errors and upgrade stops.
Despite this error, roundcube works but last time (upgrade from 
0.9.5+dfsg1-4.2 to 1.1.1+dfsg.1-1), all was broken.
I had have to purge roundcube packages and reinstall from scratch.

The error message :
Paramétrage de roundcube-core (1.1.2+dfsg.1-5) ...
dbconfig-common: writing config to /etc/dbconfig-common/roundcube.conf
dbconfig-common: flushing administrative password
dpkg: erreur de traitement du paquet roundcube-core (--configure) :
  le sous-processus script post-installation installé a retourné une 
erreur de sortie d'état 255
dpkg: des problèmes de dépendances empêchent la configuration de roundcube :
  roundcube dépend de roundcube-core (= 1.1.2+dfsg.1-5) ; cependant :
  Le paquet roundcube-core n'est pas encore configuré.
