bug versioning and ignored NMUs

[Andreas Barth <aba@not.so.argh.org>]

Hi,

I noticed that ignoring an NMU can make bugs to "disappear", e.g. bugs
#321669 and #295270 - as they were reported against NMUed versions, they
just vanished for unstable.

Well, what do against this (apart from cluebatting maintainers :) is of
course a good question. One could just say that a bug reported against a
version is always open in any newer version as long as it is not fixed
at all. This is however problematic in two ways:
* sometimes, bugs are really stable-only, e.g. a broken security upgrade
* even if the assumption above is true, what happens with the bug if it
  is fixed with some point release. That shouldn't have any effect on
  the bug count of the unstable version.


Cheers,
Andi
