The above compiles without problems for me (valac 0.14.0). This error
probably means that you are trying to use this variable from a lambda
expression.

Another solution is to use libgee: libgee's lists are objects and
don't need any special treatment (just pass them normally and you can
call list.add with no problems)

HTH,
