You might be able to replace the relevant calls using an LD_PRELOAD 
library.  There's an article about doing this sort of thing in the Linux 
Journal:
    http://www.linuxjournal.com/article/7795

I think the best point of attack would be the gtk_dialog_run() function. 
 My development steps would be:

Step 1: write an LD_PRELOAD library as described above that contains a 
replacement gtk_dialog_run().  Initially just have it call the original 
gtk_dialog_run().

Step 2: link your LD_PRELOAD lib against GTK+ and see if you can query 
the type of the dialog without it crashing or something.

Step 3: change your function so that when it is passed a 
GtkFileChooserDialog it returns GTK_RESPONSE_CANCEL immediately instead 
of calling the original gtk_dialog_run().

Step 4 (optional): rather than just canceling, call 
gtk_file_chooser_set_filename() and return GTK_RESPONSE_ACCEPT to have 
the file saved somewhere.  May be required if the cancel response stops 
the app from doing further processing.
