Hi Markus, could you please try out, if the problem is fixed with a patched libproxy?
$ echo deb https://deb.debian.org/debian/ experimental main \ | sudo tee /etc/apt/sources.list.d/experimental.list $ sudo apt update $ sudo apt install -t experimental libproxy1v5 (IIRC) It would be very helpful to know, if this fixes the annoying Gajim crash. Thank you!
