Getting two warnings with this:

Address.cs(28,4): warning CS0278:
`System.Collections.Generic.IDictionary<string,string>' contains
ambiguous implementation of `enumerable' pattern. Method
`System.Collections.IEnumerable.GetEnumerator()' is ambiguous with

gmcs -debug  -out:monitor.exe -t:exe   -r:../src/NDesk.DBus.dll  Monitor.cs
Monitor.cs(66,3): warning CS0278:
contains ambiguous implementation of `enumerable' pattern. Method
`System.Collections.IEnumerable.GetEnumerator()' is ambiguous with

It's also be nice if make install worked...
