Problems with data returned from Gtk2::SimpleList

[ new subject, since this has nothing to do with the original thread ]

Subject: RE: capturing output from running process crashes gtk2

How do I write

     my $filename = $list -> {data}[$page[0]][0];
     $image = Gtk2::Image -> new_from_file ($filename);

on one line?

     $image = Gtk2::Image -> new_from_file ($list -> 

doesn't work.

I'm guessing $list here is a Gtk2::SimpleList?
I can confirm this behaviour: $list->{data}[0][0] correctly
contains the expected value in row 0 and column 0 
(assuming column 0 is of type "text"),
but when it is directly fed into Gtk2::Image->new_from_file
nothing is shown in the returned image (not even the "broken image"

Now Gtk2::Image->new_from_file is apparently just an XS wrapper
for gtk_image_new_from_file... Looking at $list->{data}[0][0]
with Devel::Peek I can see it contains some heavy magic
(it's actually an lvalue), maybe it isn't correctly
converted down to a simple string when passed from
Perl to C level?
