It always irks me when someone doesn't at least translate the error output he gets and expects things to be fixed... Why bother reporting then? Anyway...
version: gufw 17.04.1-3 (community repo)
I get the same problem. Python segfaults:

Comment by Levente Polyak (anthraxx) - Tuesday, 17 January 2017, 16:56 GMT

can't reproduce. Are you running x11 or wayland?
Can you try using a a default theme like Adwaita?
If that doesn't help, please report this issue upstream and add a reference over here :)

Comment by fuan_k (fuan_k) - Tuesday, 17 January 2017, 17:01 GMT

Using x11, same result using Adwaita.

Using i3wm, with XFCE's xfsettingsd running. Same problem under XFCE.

Edit: tested with another install running KDE, it works fine there. Very strange.

Comment by Levente Polyak (anthraxx) - Tuesday, 17 January 2017, 17:24 GMT

Can't get it to reproduce anywhere on multiple environments... please really report this upstream :/

can you also dump your exact package versions of:
python
python-gobject
gdk-pixbuf2
gtk3

Using x11 and Adwaita

python 3.6.0-2
python-gobject 3.22.0-2
gdk-pixbuf2 2.36.4-1
gtk3 3.22.7-1

Running 'gksudo gufw-pkexec' works without problems.

Comment by fuan_k (fuan_k) - Tuesday, 17 January 2017, 17:59 GMT

Alright, I think it's clear that it's a python2/3 issue.

I ran
sudo python3 /usr/lib/python3.6/site-packages/gufw/gufw.py

And it started fine. Clearly a problem with my default python environment.
gksudo gufw-pkexec does work indeed.

nupupun@P5E> cat $(which gufw-pkexec)
#!/bin/bash
LOCATIONS=(
"/usr/lib/python3.6/site-packages/gufw/gufw.py"
"/usr/lib/python3.6/dist-packages/gufw/gufw.py"

)

for ((i = 0; i < ${#LOCATIONS[@]}; i++))
do
if [[ -e "${LOCATIONS[${i}]}" ]]; then
python3 ${LOCATIONS[${i}]} $1
fi
done

Try running with GDK_BACKEND=x11 .

I've changed my theme to Adwaita, and executed "export GDK_BACKEND=x11", but I still get the same segfault error:

Comment by Balló György (City-busz) - Sunday, 05 February 2017, 14:30 GMT

The problem is that gufw requires to run as root, but root applications don't have access to the Wayland compositor for security reasons. This affects all GUI applications that run with 'sudo' or 'pkexec'.

Comment by Levente Polyak (anthraxx) - Sunday, 05 February 2017, 14:36 GMT

^ thats why my first question was if its wayland or x11, but fuan_k seems to use x11

Comment by Polo (powlow) - Tuesday, 14 February 2017, 14:37 GMT

As a temporary workaround I just edited the /bin/gufw file:

````
#!/bin/bash
#c_user=$(whoami)
#pkexec gufw-pkexec $c_user
gksudo "python3 /usr/lib/python3.6/site-packages/gufw/gufw.py"

Could you try again with English? Most of the people on this bugtracker and all of the people in this ticket (including the package maintainer) aren't chinese and English is the accepted standard for communicating in international fora...
