[VM] Emacs24: "Marker points into wrong buffer"

[Rene]

I just upgraded emacs24 (emacs-snapshot 2:20130831-1~bpo70+1 taken from
http://emacs.naquadah.org/) which works great.

But it turns out that VM now invariably run into the following problem:

           "Marker points into wrong buffer"

which prevents me from reading/dealing with old and new emails.

Do you know how I can fix this problem?
