How horrid.

If I correctly read the Debian maintainer's post in the bug you 
linked[0], it's possible to revert only the libImageProcessor 
infec^Waddition. If it's all right with everyone, I'd like to give 
that a try first. Say by tomorrow? Or do you want to revert first 
& ask such questions later?

Nice. I wish it worked.

Aside, -ish: looks like most distributions there found out about 
this file due to some failing sanity check. Perhaps we could add 
our own, in ‘guix lint’ or at build time, to warn about ELF files 
and other suspicious binaries in post-snippet sourceballs?

No idea if it's worth the trouble/performance hit/false-positive 
rate, of course. That's for the ner^Wgods to decide.

Kind regards,

T G-R
