Subject: Re: bug#65383: [gnome-team] Nothing is reproducible anymore

The culprit has been found [1] and arrested [2].  It turns out that the
ungexp Bruno used at the time was "too wide", resulting in a new .drv
for shared-mime-info each time.  This wasn't caught during review,
because who has time to build things twice?

What are the lessons learned from this?
1. Closely look at when and how you use ungexp.
2. Actually build things multiple times ;)
Perhaps we can also add this to the things to check in continuous
integration, though with the fair amount of known unreproducible
packages, I'm not so sure of how great this will go.

Anyway, thanks for your attention.

Cheers
