+Summary: Segmentation fault in simple plugin framework
+
+Description of Problem:
+I've created a simple plugin framework that works great in .NET (2.x). The
+same application gives me a segfault with mono 1.2.2.1/JIT 0.31.
+
+Steps to reproduce the problem:
+1. extract provided sample.
+2. run "sh build.sh"
+3. run "sh run.sh"
+
+Actual Results:
+[HostApp] Loaded PluginOne (r1)
+[PluginOne] OnMessage(test1)
+[PluginOne] OnMessage(hi there)
+[PluginOne] OnMessage(wassup?)
+[PluginOne] OnMessage(the end :()
+[HostApp] Unloading PluginOne
+[PluginOne] Dispose()
+run.sh: line 2:  2547 Segmentation fault      mono hostapp.exe
+"$PWD/plug.dll" PluginOne.PluginOne
+
+Expected Results:
+[HostApp] Loaded PluginOne (r1)
+[PluginOne] OnMessage(test1)
+[PluginOne] OnMessage(hi there)
+[PluginOne] OnMessage(wassup?)
+[PluginOne] OnMessage(the end :()
+[HostApp] Unloading PluginOne
+[PluginOne] Dispose()
+[HostApp] Loaded PluginOne (r1)
+[PluginOne] OnMessage(test1)
+[PluginOne] OnMessage(hi there)
+.....
+
+How often does this happen? 
+All the time.
+
+Additional Information:
+Feels like MarshalObjectByRef is the cause, but it works like a charm on .NET
