Is StatusNotifier spec. implemented in MATE 1.8 (Mint 18.2)

[oblongau]

Expected behaviour

Running calibre (https://calibre-ebook.com/) as:
calibre --start-in-tray
should result in calibre starting minimized to system tray
(https://manual.calibre-ebook.com/generated/en/calibre.html)

Actual behaviour

calibre starts and stays open as a window. If started in a terminal, this message appears:
"Failed to create system tray icon, your desktop environment probably does not support the StatusNotifier spec"

Steps to reproduce the behaviour

Install calibre from calibre site.
Test by running, as normal user, in terminal:
calibre --start-in-tray

AFAIK, yes. If not, you can use my 3rd-party applet.

Hello,

It is implemented but it is disabled by default on Linux Mint. You could update the "enable-sni-support" from false to true with Dconf.

Best regards.

Thanks again. I installed dconf-editor, ran it to set org>mate>panel>general>enable-sni-support

But at boot time there is now a pop up:
"Notification Area" has quit unexpectedly. If you reload a panel object, it will automatically be added back to the panel."

The network connection/speaker etc. icons are then not showing. If I click "Reload" then they reappear. There is no indication there that calibre is running, but it is actually properly running in the background.
dmesg has this entry:

The panel size is 25 pixels, if that is a factor.

Any ideas as to what next?

OK, could you close this bug and open another one for the segfault? We need to have all the requested data to help you (the bug template).

It shouldn't be segfault.

Best regards.

Hopefully this is what you mean:
