An exception when Intellisense is invoked

Hi guys,

I am getting this exception when I type . after a variable name (when Intellisense is supposed to appear). I see that this problem appears only with variables defined within the snippet (I use header and footer to define the class and method) while Intellisense on method arguments (defined in header) works as expected.
