I've updated the bug-report with the above text as well as my results
of a bisection of libfetch. 
Looking at the patch, the change in libfetch seems sensible and I
suspect that something higher up the chain is calling it in a wrong way.

As far as I can tell, it is possible, that pacman never called libfetch
in The Right Way (TM), but this only got exposed, after libfetch
stopped closing connections unconditionally.

Let's hope that some of my stumbling around is actually helpfull :)
