You have dialog as a class attribute on your choosefile class, so it's
only instantiated once. Since you call dialog.destroy() in the run
method, and then try to rerun the dialog, the crash is not surprising.

There are a couple of ways to fix this. I'd explicitly make choosefile
a singleton and use dialog.hide(), but you could also make it an
instance variable (by creating in choosefile's __init__ method) and
thus recreate the file chooser on each run.
