Emilio, I can reproduce this in bookworm by compiling webkit2gtk with 
libc++-16 there.


Plan A would be that someone (not me) debugs what is going wrong in
libproxy when libc++-16 is linked.

libproxy in trixie is a complete rewrite in C, which makes upstream 
support for fixing unlikely.


Plan B would be
  Package: libwebkit2gtk-4.0-37
  Breaks: libproxy1-plugin-networkmanager

This would not be nice, but better than runtime breakage.

This would likely also be needed in bookworm if we ever need libc++ there.
