Segfault with GnomeCanvasWidget, test case

[Aaron Lehmann <aaronl vitelus com>]

Hi,

GnomeCanvasWidget has not been working for be at all. I have tried many
things but it always either segfaults or doesn't display anything. I have
attatched a simple program (compilation instructions in header) that
produces a segfault when run on my machine. Can anyone fix it or
gnome-libs so it doesn't segfault?

Bonus: If you can get it to stop segfaulting, can you get it to actually
display the label?


Thanks,
Aaron Lehmann
