If I understood it correctly libproxy is only used by glib
networking code when not running GNOME.

This has been reported upstream:

https://github.com/libproxy/libproxy/issues/199

Also these apparently describe the same bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970687
https://github.com/exaile/exaile/issues/737

Both workarounds mentioned in those bug reports (removing either
/usr/lib/x86_64-linux-gnu/gio/modules/libgiolibproxy.so or
/usr/lib/x86_64-linux-gnu/libproxy.so.1.0.0) fix the crash and
gajim successfully connects.
