Has anyone ever put a FileSelectionBox inside a PanedWindow? I have
FileSelectionBox inside a form, inside a PanedWindow.  When I run the
code, I either get a core dump or the error message 'Widget "(null)"
has no windowed ancestor', even though it does. If I use a RowColumn
instead of a PanedWindow, it works fine, or if I have PW -> RC -> Form
-> FSB.
