moodle/blog/lib.php line 353 [CONTEXT_USER+1]
moodle 8.1 build 20141113

==============
function blog_get_all_options(moodle_page $page, stdClass $userid = null)

// ===== removed a bunch of code ====

if ($user !== null and !isguestuser($user)) {
// Load for the requested user.
$options[CONTEXT_USER+1] = blog_get_options_for_user($user);
)

================
the +1 caught me off guard, i was doing a search in all files for "CONTEXT_" to see uses of it. and i only saw changes in "test doings" never a regular function. let alone a + anything.

this maybe just a "noob" huh? and not an actual bug. but i honestly do not know. i am not familiar enough with moodle code let alone the blog code.
