[Pkg-utopia-maintainers] Bug#933698: network-manager-gnome: nm-applet fails to detect NetworkManager, possible race condition?

[James Tocknell]

Package: network-manager-gnome
Version: 1.8.22-2
Severity: important

It appears that sometimes nm-applet doesn't find the NetworkManager daemon (or
dbus interface or something), and states "NetworkManager not running". Given I
can see that NetworkManager is running (via nmcli), and I'm connected to the
network, and that if I kill nm-applet and start it up again and it find
NetworkManager running, I'm guessing there's some sort of race condition between
when nm-applet checks for NetworkManager availability and NetworkManager
actually running (or starting the dbus interface or which ever). This is a new
problem (1.8.20 didn't have this problem or at least I never triggered it), I'm
not confident enough yet to call it a regression. Would it be possible to get
nm-applet to poll for NetworkManager's existence if it appear to be not running?
