No, it's an English/US setup.  I am using Win98, if that would make a
difference.

When go to a window created by "MS-Dos Prompt" and run it from the
command line, it crashes.  If I run it from the command line in the msys
window, it executes seemingly correctly.

I do believe it is rxvt.  It does seem odd that it's working this way.
I get 4 lines of error messages (I'll go into windows and get the exact
filenames and line #'s when I get the chance) - but surely at least
_someone_ else should be getting the same errors.  These messages all
appear to be caused by the fact that pointers to strings - filename and
pathnames - are supposed to be passed but a NULL pointer is getting
passed instead.

Please excuse my ignorance, but where is this bugzilla.  I scanned your
webpage looking for a bug list but didn't find one.

I'll include a rudimentary program I wrote to test this problem.

------------------ cut --------------------------
#include <gtk/gtk.h>

int main(int argc, char * argv[])
{
    GtkWidget *window;
    GtkWidget *dialog;
    
    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(G_OBJECT(window), "destroy",
                     G_CALLBACK(gtk_main_quit), NULL);

    dialog = gtk_file_chooser_dialog_new("File Chooser dialog",
                                         GTK_WINDOW(window),
                                         GTK_FILE_CHOOSER_ACTION_OPEN,
                                         GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
                                         GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
                                         NULL);
    /* This line added to see if it would help - it didn't */
    gtk_file_chooser_set_filename(GTK_FILE_CHOOSER(dialog),"");
    gtk_dialog_run(GTK_DIALOG(dialog));
    gtk_widget_destroy(dialog);
                                         
}
