Waybar: nm-applet segfault error

Created on 5 May 2019 · 10Comments · Source: Alexays/Waybar

Hi,

first of all: thx for waybar ! It was the missing piece I needed to migrate from i3 to sway!
However, one app doesn't work like expected. nm-applet keeps segfaulting reproducibly on trying to connect to unknown wifi networks:

 ~ $ nm-applet 

(nm-applet:11642): Gtk-WARNING **: 17:03:07.720: Can't set a parent on widget which has a parent

here's the regarding system log:

Any idea how to fix this ?

it works if you force it to use X11 for the windows:
GDK_BACKEND=x11 nm-applet --indicator

That's not a waybar fault :/

@Alexays ok, but could you please point me in a direction here ? Do I need to file a bug for wayland, sway, nm-applet, or sth else ?

nm-applet works just fine with i3 btw.

This issue appears to have been fixed in upstream with nm-applet 1.8.24: https://gitlab.gnome.org/GNOME/network-manager-applet/blob/58946f0f5c1f84ae4136e6d417870572bfd45cd5/NEWS

There shouldn't be any need to run it with GDK_BACKEND=x11 anymore, even though the corresponding https://gitlab.gnome.org/GNOME/network-manager-applet/issues/64 hasn't been closed.
