[Pkg-utopia-maintainers] Bug#815313: network-manager-gnome: nm-applet crashes after connecting to OpenConnect VPN

[Mike Kupfer]

Package: network-manager-gnome
Version: 1.1.90-3
Severity: normal

Dear Maintainer,

I have an account on an OpenConnect (AnyConnect) VPN.  I can
successfully connect to the VPN, but when I do, nm-applet dies.  It
leaves behind a core file with the following stack trace:

#0  0x00007fc701ef3507 in raise () from /lib/x86_64-linux-gnu/libc.so.6

I see these messages in .xsession-errors, though I'm don't know if any
of them are relevant (other than the one about
applet_get_first_active_vpn_connection assertion failure):

  ** (nm-applet:6746): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
  [...]
  nm-applet:ERROR:applet.c:1227:applet_get_first_active_vpn_connection: assertion failed: (s_con)
  Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
  [...]
  ** Message: vpn: (openconnect,/etc/NetworkManager/VPN/nm-openconnect-service.name) cannot load legacy-only plugin

Hmm.  That last message ("cannot load legacy-only plugin") probably
explains why I can't edit the configuration for the VPN account...

This is with Xfce.

The workaround is to restart nm-applet.
