Applet can't register with dbus

[ghost]

The applet compiles withought errors .
Desktop : Mate 1.18
Versions tried : 0.9 and 0.10
Distro: Manjaro
When I run the applet I get this error :
Could not register service
after eval $(dbus-launch) the error is not displayed anymore .
The applet renders on the panel but no notifiers .
Notes : Using ubuntu's patched libdbusmenu lib from AUR

Do you have notification area applet on the panel? Mate 1.18 has it own implementation of StatusNotifierWatcher which conflicts with snw-plugin.

Yes I have . But this is wath I did :

1. Remove the notification area applet
2. Restart mate so dbus restarts asswell
3. Add the snw-plugin to the panel
   But after that I get segfault:
   zsh: segmentation fault (core dumped) /usr/lib/mate-panel/snw-applet

That's strange. Core dump file should be located in /var/lib/systemd/coredump/. Could you send it to me?

Here it is .Github does not support sending lz4 compression files so here is a link to gdrive :

Ouch, I forgot that you need to build package with debug symbols. Add options=(debug !strip) to PKGBUILD. Also architecture doesn't match.

If have experience with gdb, you can get stack trace by yourself. First, remove applet from panel. Then launch /usr/lib/mate-panel/snw-applet inside gdb, add applet to panel and reproduce a segfault.

Alternatively you can just send me core dump file with snw-applet binary.

Well I have never debuged until now :D

Replecated it by removing notification area applet while snw-applet is running .

Hope this is wath you are looking for :
