[Pkg-citadel-devel] Bug#646403: groupdav: serious data loss when using external clients

[T. Ulbricht]

Package: citadel-server
Version: 7.86-1
Severity: critical
Justification: causes serious data loss


Using citadel with webcit and an external client, like the thunderbird 
lightning extension (1.07b) 
renders citadel unusable as a calendar groupware application.  
Randomly, when I delete or add an appointment into a remote calendar using
lightning, the calendar entries are all completely gone.

This is serious data loss!

Since there is no real backup strategy for the normal user, all one can do as
a workaround is recovering from a backup (again data loss since last backup) 
roll back from within the Berkeley db, which is undocumented and involves 
some guessing when the incident happened!

I installed the testing versions of 
citadel-client/wheezy uptodate 7.86-1
citadel-mta/wheezy uptodate 7.86-1
citadel-server/wheezy uptodate 7.86-1
citadel-webcit/wheezy uptodate 7.86-dfsg-1
libcitadel-dev/wheezy uptodate 7.86-1
libcitadel2/wheezy uptodate 7.86-1
into a stable debian.

Thanks!
