 Are you using current SVN?  Because I just fixed this exact same issue
 recently, and I can't duplicate the crash here.

+I updated to SVN again and still get the crash, maybe it is Windows
+only?  Anyways, I ran it in debug to find the line it's crashing on. 
+In the following block (roughly line 2128):
+
+if (update_caret) {
+  // Move caret to the end of the inserted text
+  if (insert_lines > 1) {
+    Line l = GetLine (line.line_no + insert_lines + 1);
+    PositionCaret(l, l.text.Length);
+  } else {
+    PositionCaret(line, pos + ins[0].Length);
+  }
+  if (owner.IsHandleCreated) {
+    XplatUI.CaretVisible(owner.Handle, true);
+  }
+}
+
+It is crashing on the line:
+    PositionCaret(l, l.text.Length);
+because l is null. 
+ 
+line.line_no = 1, insert_lines = 3
+
+The text that happened to be in my buffer this morning when I tried it
+ is between the following lines:
+-----------
+		[Browsable (false)]
+		[EditorBrowsable (EditorBrowsableState.Never)]
+-----------
+
+Also, I get the error both by pasting with Ctrl-V and using the
+context menu Paste.
