Hi, The following program causes a Segmentation fault.

import gio

class A:
    def __init__(self):
        self.s = gio.File("http://www.gnome.org/~jstowers/conduit_test_data/Image.png")
        self.d = gio.File("b.png")
        self.canc = gio.Cancellable()

    def progress(self, current, total):
        print current,total

    def copy(self):
        ok = self.s.copy(
                destination=self.d,
                flags=gio.FILE_COPY_OVERWRITE,
                cancellable=self.canc,
                progress_callback=self.progress
                )
        print "OK? %s" % ok

a = A()
a.copy()

Observations:
I think this error goes away if the file exists, and seems to be due to something getting cleaned up before the write to disk has finished...
