Runtime error

[Utpal Shasane <shasane_utpal extenprise net>]

Hello,
I am trying to print the file name from file selection dialog box by using
printf ("%s\n",gtk_file_selection_get_filename (GTK_FILE_SELECTION (fs)));
I am getting following error
Gtk-CRITICAL **: file gtkfilesel.c: line 1242 
(gtk_file_selection_get_filename): assertion `GTK_IS_FILE_SELECTION 
(filesel)' failed

Please, anybody can figure out what's wrong with this...
Thanks,
/utpal
