Thank you Horst,

Unfortunately, this has a near zero chance of even being looked at by
Daniel for various reasons. The foremost being that its a patch against
a debian version of 2.02, and not current master. The patch is also not
in an acceptable form for this list (see other patches submitted here).

I've looked at the issue and it is a little worrying. I'm surprised
there haven't been more complaints or that I've not yet run into this
(I suppose I nor many others have a VG that has been changed more than
220 times). I'll submit a proper patch to the list to get the ball
moving on this.
