[sylpheed:30923] [BUG]folderview_{width, height} not saved when mainwin_maximized

[Laurent Bigonville]

Hi,

I think there is a bug the way sylpheed handle the save of the size of
some widget.

The main_window_get_size() function returns without saving some
width and height if the main window is maximized.
