+Summary: NullReferenceException on two members of System.Environment
+
+Description of Problem:
+
+Two members of System.Environment, one of which my nice happy fun IRC
+class library relies on, give NullReferenceExceptions when my application
+attempts to access them. :-(
+
+To reproduce the problem:
+
+namespace Test1
+{
+ class Class1
+ {
+ static void Main(string[] args)
+ {
+ Console.WriteLine
+(Environment.SystemDirectory.ToString());
+ Console.WriteLine(Environment.OSVersion.ToString
+());
+ }
+ }
+}
+
+Both of these members cause this error. :-(
+
+Actual Results:
+
+For the code that produces this error,
+
+(process:1960): ** WARNING **: unhandled exception
+System.NullReferenceException
+: "A null value was found where an object instance was required"
+#0: 0x00014 callvirt in Test1.Class1::Main ([00C26F60] )
+
+(using mint -- similar error using mono) I'm guessing the static
+Environment constructor is just missing initialization for these. :-)
+
+Expected Results:
+
+I was expecting my test console IRC client to happily use the library and
+connect. ;-) Well, this sample program I was expecting to print out two
+lines and exit. Ah well. :-)
+
+How often does this happen?
+
+Every time.
+
+Additional information:
+
+If you need to take a look at the source for the original thing giving
+the bug, you can pick it up at http://www.illusorystudios.com/coding/.
+The console IRC client is at the 'Sample Code' link. Either way, at least
+using Microsoft's C# compiler the above code gives an error. I haven't
+tried mcs. VS.NET IDE is too precious to me. :-)
