What about all the errors/warnings, have they gone, or do they still appear?
Did the errors appear the first time the dialog was opened, or only
when the dialog was re-opened?

Using gtk_widget_hide instead of gtk_widget_destroy is quite likely
only hiding the errors - the errors are still there and just waiting
to crash your code more seriously.

Take a look at the typical usage examples of the
GtkFileChooserDialog[1] in the documentation. If you still have
problems we'll probably need to see the code.
