Hallo,
in my programm I've got the following global pointer:
void
on_fileselectionfensterglobal_destroy (GtkObject *object, gpointer user_data)
{
...
gtk_widget_destroy (fileselectionfensterglobal);
}
You're not assigning anything to 'fileselectionfensterglobal' so of course its value is not going to be NULL.
After you destroy it, you need to set
"fileselectionfensterglobal = NULL;"
