+ * This fixes an issue in GOutputStream that applies the atomic replace

+ * when the stream is closed. However, there is no way currently to tell
+ * the stream that the save should be aborted (there could be a
+ * conversion error). The patch explicitly closes the output stream
+ * in all these cases with a GCancellable in the cancelled state, causing
+ * the output stream to close, but not move the file. This makes use
+ * of an implementation detail in the local gio file stream and should be
+ * properly fixed by adding the appropriate API in gio. Until then, at least
+ * we prevent data corruption for now.
+ *
+ * Relevant bug reports:
+ *
+ * Bug 615110 - write file ignore encoding errors (xedit)
+ * https://bugzilla.gnome.org/show_bug.cgi?id=615110

+ * @short_description: message type description
+ * @include: xedit/xedit-message-type.h
+ *
+ * A message type is a prototype description for a #XeditMessage used to
+ * transmit messages on a #XeditMessageBus. The message type describes
+ * the Object Path, Method and Arguments of the message.
+ *
+ * A message type can contain any number of required and optional arguments.
+ * To instantiate a #XeditMessage from a #XeditMessageType, use 
+ * xedit_message_type_instantiate().
+ *
+ * Registering a new message type on a #XeditMessageBus with
+ * xedit_message_bus_register() internally creates a new #XeditMessageType. When
+ * then using xedit_message_bus_send(), an actual instantiation of the 
+ * registered type is internally created and send over the bus.
+ *
+ * <example>
+ * <programlisting>
+ * // Defining a new message type
+ * XeditMessageType *message_type = xedit_message_type_new ("/plugins/example",
+ *                                                          "method",
+ *                                                          0,
+ *                                                          "arg1", G_TYPE_STRING,
