[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?

If it works fine on a public release of Emacs, but not the development
version, the problem is likely to be with the development version.

We will need to report it when the development version is closer to release.

I'm not sure. I notice this problem only seems to occur with VM.

Better report it sooner than later.

"Marker points into wrong buffer"

IIUC this means that you're using a marker's position in another buffer
than the one it's pointing to.

While the change might be a bug in the development code of Emacs, it
might also point to a harmless bug in VM that simply wasn't
detected earlier.

You're exactly right.

This happens whenever the marker in the summary buffer points to an email
that is different from the one already displayed.

Once this error happens then VM behaves eratically. It becomes impossible
to get back to a steady state.

I experienced this issue as well. I removed my .vm.preferences file,
leaving just the 'core' stuff in my .vm and the problem whent away. Have
not tried tracking down exactly what in my .vm.preferences file is causing
the issue, but I suspect it is the bits to deal with message threading.
Just mention it in case someone is looking into this as not sure when I'll
have time to look closer.

I just removed this line

(vm-summary-faces-mode 1)

from my .vm.preferences and the problem went away.

Now I'm back with the latest version of emacs24.

Thanks.
