** Description changed:
A dialog with the following text appears anytime I try to wipe my usb

+
+ [Impact]
+
+ * This bug is a runtime exception caused by invalid erase type.
+ * With this bug users can not erase disks with usb-creator.
+
+ [Test Case]
+
+ * Prepare an usbstick with any partition(s),
+ this could be done with "gparted".
+ * Launch usb-creator-gtk or usb-creator-kde.
+ * Insert the usbstick, click the button "Erase Disk".
+ * It will popup an exception window with the error message similar to:
+
+ Traceback (most recent call last):
+ File "format.py", line 7, in <module>
+ block.call_format_sync('dos', GLib.Variant('a{sv}', {'erase':
GLib.Variant('s', '')}), None)
+ gi._glib.GError: GDBus.Error:org.freedesktop.UDisks2.Error.Failed:
Error erasing device: Unknown or unsupported erase type `'
+
+ * Please be noted, the erase operation may still fail even with
+ this bug properly fixed due to some other bugs, such as bug #1318954.
+
+ [Regression Potential]
+
+ * Since the erasing operation is also blocked by other bugs,
+ we may not be able to verify the entire erasing operation,
+ in such a case we can not promise the effect of the patch,
+ and it may (although not sure to) has other side effect such as:
+ * The patch for this bug changes the erase type to "zero",
+ according to the UDisk2 API [1] it will erase the entire device,
+ this may cause a long time to complete.
