[Gambas-user] Dbus unique name seems incorrect

[Bruce Steers]

My 2 bits worth Brian, not even sure if it's related but,   i had issues
with DBus.Unique when i added a SystemTray object.

The Systemtray initialized DBus before i tried to set the name so it was
too late.
i fixed it by setting the DBus name and unique flag in the classes _new()
or _init() methods.

So if your app has any DBus objects be aware of that.

All the best.
