+Summary: mono crashes with segfault in mono_marshal_get_native_wrapper
+
+Description of Problem: 
+ 
+When running (new) Qt# apps, mono aborts with the following: 
+ 
+0x080d2d63 in mono_marshal_get_native_wrapper (method=0x82618b0) at 
+marshal.c:2186 
+2186                            if (t->data.klass->delegate) { 
+ 
+Per Paolo's instructions, I did 
+ 
+print t 
+ 
+$1 = (struct _MonoType *) 0x8261918 
+ 
+print *t 
+ 
+$2 = {data = {klass = 0x0, type = 0x0, array = 0x0, method = 0x0},  attrs = 0, 
+type = 28, num_mods = 0, byref = 0, pinned = 0, modifiers =  0x8261920} 
+ 
+Paolo had me change line 2186 in marshal.c to 
+ 
+if (t->data.klass && t->data.klass->delegate) { 
+ 
+and that fixed the problem.
