Okay, I found it in the latest CVS source code.
The problem happens in approximately line 760 of interface.cs. The
variable "builder" is null at that point.
This means precisely nothing to me, but hopefully it will help you to
help me :)
 mono --debug reported it as line 766 which threw me a little,
because that's the line number of the *next* statement. I put in a
Console.WriteLine before line 766 and it never happened, but a
Console.WriteLine before line 760 listed builder as null, which is
consistent with the NRE because line 760 tries to call a method on
builder. Is this a known bug in mono --debug's reporting of line numbers?
