I've just found

#define g_mapped_file_unref g_mapped_file_free

in gst-libs/gst/tag/lang.c, so I think this bug can be closed, Can some gstreamer devel confirm?

I see no use of g_mapped_file_unref in the code you pasted here. I ain't no GStreamer dev, but this is IMHO a duplicate of bug 560442 which states (see http://bugzilla.gnome.org/show_bug.cgi?id=560442#c11 ): 

"Use g_mapped_file_unref if Glib >= 2.22 is available"

Hello Luis,

that patch was for gstreamer code, this is gst-plugins-base; reopening.

Fixed, thanks for the bug report:

    tests: don't use deprecated GLib API g_mapped_file_free
    
    Fixes #605100.

Sorry Javier, You're right. I think I should not try to triage bug at 4 in the morning :-p

Commit on 2010-03-30 added usage of g_io_channel_read:

$:andre\> grep -r g_io_channel_read .
./tests/examples/seek/jsseek.c:      g_io_channel_read (source, buf, sizeof (struct js_event), &bytes_read);

Hence reopening. Please consider using "-DG_DISABLE_DEPRECATED" by default.

    gst-glib.m4: Define G_DISABLE_DEPRECATED for GIT versions
    
    If deprecated API is found, for which the replacement is in
    a newer version of GLib than we currently depend on, use
    the new API in a #if GLIB_CHECK_VERSION block and remove
    that block after depending on a new enougb GLib version.
    
    Fixes bug #605100.
