Original commit message from CVS: * ext/gio/gstgiobasesrc.c: (gst_gio_base_src_create): * ext/gnomevfs/gstgnomevfssrc.c: (gst_gnome_vfs_src_create): Use gst_buffer_try_new_and_alloc() and fail properly if the allocation failed. This prevents abort() if downstream elements request an insane amount of memory.
