 This is something that confused me at first too. This is not complaining
that the widgets are NULL, but it's actually an assertion, that fails. This
sort of error should be changed to something like:
 
** WARNING **: file gtkbin.c: line 203 (gtk_bin_add): Assertion that
"bin->child == NULL" has failed.

 This often comes up when you try and pack an already packed widget, into
another widget. I can't tell the problem from the code snippet. Have any of
the widgets that are being packed, already packed ?
