Gtk2::SimpleList crashes

Originally, I tried to find a way to delete all values matching certain criteria
from a Gtk2::SimpleList (which always crashed). Eventually, I found, that I don't
have to get fancy to cause that crash - the following will do it:

    my @data= {$slist->{data}};
    @{$slist->{data}}= data;

Gtk-CRITICAL **: gtk_list_store_get_value: assertion `VALID_ITER (iter, list_store)' failed at /usr/lib/perl5/Gtk2/ line 248, <F> line 35. GLib-CRITICAL **: g_hash_table_lookup: assertion `hash_table != NULL' failed at /usr/lib/perl5/Gtk2/ line 248, <F> line 35.
Segmentation fault

Can anybody tell me what's wrong with that code snippet?
Is there any workaround?
