I think the problem is with the nm-signal-*-secure.svg images found in at least Ambiant-MATE and Radiant-MATE themes.
With strace I can see that 'mate-indicator-applet-complete' tries to open '/usr/share/icons/Ambiant-MATE/status/22/nm-signal-75-secure.svg' but after that it displays '/usr/share/icons/Humanity/status/22/image- missing.svg' instead. Opening '/usr/share/icons/Ambiant-MATE/status/22/nm- signal-75-secure.svg' with Inkscape dispalys multiple errors like this: nm-signal-75-secure.svg:34: namespace error : Namespace prefix inkscape for current-layer on namedview is not defined kscape:zoom="10.375" objecttolerance="10.0" pagecolor="#ffffff" showgrid="false" Opening with cairosvg prints: xml.etree.ElementTree.ParseError: unbound prefix: line 34, column 2 A Workaround that works for me: Inkscape, beside the errors, can open the images and by saving them, overwriting the originals, fixes the missing image problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876467 Title: Network Manager Applet Icon error on VPN Connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1876467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
