Hate to say this, but I agree with David. This is even making me
uncomfortable.

To say this clearly, I am not denying this information is not useful. Of
course it is. But I think putting this into crash reports is a) not the
right place since it has not much to do with crashes and b) has the
potential of damaging the trust of users.

More generally, I would like a clear conversation and negotiation - with
written down results - about what should and should not go into the crash
report. Otherwise this is will be a continuous source of friction. I value
an easy and trustful cooperation and trustful users more highly that
detailed crash reports (which I do value very highly! :-).

As an added benefit of such a discussion, having a Wiki page defining which
information a crash report may contain (and which not) can build trust with
our users.

Just my five cent,

Thomas
