OK, no problem.

Who raises a given issue is not a criterion. The only criterion is
wheter the issue is there or not. Since I have started using GRASS I
have found many bugs, including numerous long-standing, which nobody
has raised before. Also other folks have found bugs which I was never
aware of.

We don't need to vote on this. There is a functionality which doesn't
do what it designed for, and this results in corrupted region settings.
This is a bug. I'm not going to debate on whether 1=1 anymore.

Thanks for the offer, but you can only help someone able to fix the bug.

I didn't even try to say that the 6.2 release should be hold off till
the bug is fixed, because I know this is not realistic. There are many
bugs not fixed and this doens't make me trying to hold of the release
either. Since I remember, GRASS has been always released with known
bugs not fixed, and GRASS developers convinced me that it is inevitable
- too little people working on the project compared to size of the
codebase. Since I can't fix any bug myself I don't even dare to tell
others what to do anymore. But this doesn't mean I should not inform
others about bugs I found, wishing that soemone can fix it. I'm not
going to pretend there is no bug.

There have been many bugs squashed in gis.m recently by Michael.
Encouraged by that, until this another bug has cropped out, I've been
thinking gis.m will really become stable soon and d.m can dropped
altogether. Now that this bug is known and there is no cure for it,
until the bug is fixed, d.m should remain at least as an alternative.
I, personally, would even prefer d.m as the default GUI back, due to
this particular bug - the high risk of corrupted region settings is too
serious for me to bear it. But I'm not going to insist or argue on
that, I'll settle for what others decide for. At least don't remove d.m
until the bug is fixed.
