[Orgmode] problems with org-mode remember and VM

[Eric S Fraga]

Hi!

If I use org-remember from within a VM (emacs viewmail), I get an
error (debug output attached) due to vm-folder-directory being nil.
The variable is defined in org-vm.el but not initialised.  The problem
has existed for a long time; I've just forgotten to report it...

I can avoid the problem by setting this variable but I guess this
should work "out of the box"?  

cheers,
eric
