[Pkg-telepathy-maintainers] Bug#686835: telepathy-mission-control-5: squeeze -> wheezy upgrade makes MSN accounts disappear

[Simon McVittie]

Package: telepathy-mission-control-5
Version: 1:5.12.1-2
Severity: grave
Tags: upstream
Justification: causes non-serious data loss

Mission Control 5.12 automatically migrates MSN accounts from
telepathy-butterfly to telepathy-haze. However, the migration process doesn't
actually work if telepathy-butterfly is not installed. Instead, the
butterfly account gets disabled and marked as invalid. Empathy doesn't
display accounts that are marked as invalid (which I think is a bug -
it should present account editing UI for them so they can be resurrected -
but that's unlikely to happen before wheezy).

Because telepathy-butterfly depends on papyon which depends on Farsight
which conflicts with Farstream, is removed during the upgrade from squeeze
to wheezy. The practical result is that all MSN accounts from squeeze
disappear. It is possible to get them back, but only if you're a Telepathy
expert.

I hope to be able to fix this upstream.
