I sympathize, and I agree that it sucks.

Now, I think we are all guilty.  Rather than trying to find someone to
blame, I’m more interested in seeing why we got there and what we can do
to avoid it in the future.  Of course we can call for GNOME users to
test it, and we’ll surely do that explicitly in the future.  But IMO we
should be thankful to those who worked on this upgrade branch, and I
feel it would be unwise to sit back and add more on their shoulders.

This is wrong.  None of us is careless, and suggesting that this is the
case is really unpleasant.

Thanks to Marius, Kei, and Roel for working on the fix.
