Indeed the migration part of the story had been messed up for a while:
a couple of fixes has been done to fix it. Tests via piuparts and the absence
of any piuparts bugreport let me think that is now working with the current
distributed versions:  1.5.1-1, 1.5.1-3, and 1.5.1+ds-4 .
Your former version, according to the report is 1.5.1+ds-2, a buggy one
that was for a short while in testing or unstable: my guess is that we
can consider it as over. Otherwise, I am not sure if it is relevant
to fix this very migration as it is quite unlikely while I am not sure
how to reproduce it.

Thanks,
Jerome
