clist seg fault...

[Rok Roskar <rroskar artsci wustl edu>]

I cant figure out why the following seg faults... I would really
appreciate any ideas...

char string[100];
GtkWidget *info_list;

info_list = lookup_widget(scaling_dialog,"scaling_list");
sprintf(string,"..........");
// the next line seg faults
gtk_clist_append(info_list,string);

The clist I'm using is a 1-column clist if that has anything to do with
it... thanks for the help...
