Cannot generate proxy for two dbus interface with the same names but in difference namespaces

[Matt Guo]

E.g.
I firstly declare:

namespace org.gnome.Tomboy
{
     [Interface ("org.gnome.Tomboy.RemoteControl")]
     public interface IRemoteControl {...}
}

namespace org.gnome.Tasque
{
     [Interface ("org.gnome.Tasque.RemoteControl")]
     public interface IRemoteControl {...}
}

Then if I later get both org.gnome.Tomboy.IRemoteControl and org.gnome.Tasque.IRemoteControl with "bus.GetObject<T> (busName, path)", an exception will thrown and saying:

Solution: in "ndesk-dbus-0.6.0/src/TypeImplementer.cs", Ln37, (or search "declType.Name")
change declType.Name to declType.FullName
Then this bug is gone.

[Robert Dyer (psybers)]

I can confirm both the bug and the solution. Thanks Matt!

[Alex Launi (alexlauni)]

I can also confirm this small fix fixes the bug.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ndesk-dbus - 0.6.0-3

---------------
ndesk-dbus (0.6.0-3) unstable; urgency=low

  * debian/patches/10_namespace-support.dpatch: Backport patch from upstream
    bug#377672 to fix a crash in the case where we were dealing with
    interfaces which had the same name in different namespaces. Thanks to Matt
    Guo for the fix (LP: #377672)
  * debian/control, debian/rules: Use mono-csc as compiler, bump mono-devel
    versioned build-dep to one which provides this
  * debian/control, debian/README.source: Standards-Version 3.8.3; add
    README.source
