My suspicion is that following:
libwnck is failing on a call to gdk_pixbuf_scale_simple() in the function default_icon_at_size() in libwnck/xutils.c in the libwnck source.
If you're comfortable editing source etc... I'd be interested to see what happens if you placed a
g_assert(scaled);
immediately following the call to gdk_pixbuf_scale_simple() in that function.
