Thanks for the bug report. GList methods are quite special in the way
you have to call them in C. I'd currently not recommend you to use them
in settable properties as I haven't evaluated yet how they are best
handled regarding ownership/memory management. The List methods should
work fine in non-property contexts (fields or local variables), though.
