SIGSEGV on ethernet re-connection

[andrhua]

Since recently cmst crashes after ethernet cable replugging (or equally, toggling Powered state in Technologies)
fish: “cmst &” terminated by signal SIGSEGV (Address boundary error)
Not really sure what could have caused this, connmanctl monitor on output looks fine to me:

Service      ethernet_d481d75b5b85_cable Domains = [  ]
Manager                           State = ready

Happens both in i3 and bspwm, with and without custom Qt theme, on latest stable Arch kernel 5.8.1-1.

cmst --version
CMST - Connman System Tray 2020.04.12-1

I've tried power on/off and plugging/unplugging the Ethernet cable, with and without the notification daemon and system tray notifications toggled and I can't duplicate this. I'm also running Arch although on 5.8.3. Can you start cmst from a terminal (shutdown any running instances first) then try to trigger the error. If it happens post the output you get to the terminal.

Strangely enough but bug seems to disappear with 5.8.3 kernel
