[Pkg-roundcube-maintainers] Bug#754365: roundcube-core: reinstall of roundcube fails

[Christoph]

Package: roundcube-core
Version: 0.7.2-9+deb7u1
Severity: normal
Tags: d-i

Dear Maintainer,

I try to reinstall roundcube, but it alway fails with errors in the post or perinstall scripts.
I already purged the package several times in different ways.
Also removed all remains manually.
Last i tried to clean up debconf database by PURGE deconf-communicate, but didn't help.

Last snippet of the dpkg-output with -x in the scripts:
apt-get install roundcube

roundcube is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
2 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue [Y/n]? y
