This doc says:
http://developer.gnome.org/doc/API/2.0/glib/glib-IO-Channels.html#g-io-channel-read-line

"str_return will contain allocated memory if the return is
G_IO_STATUS_NORMAL"

That means every time g_io_channel_read_line is successfull; you
have some newly allocated memory.

It is up to you to free that memory, yes.
