I was just testing a bug enrolling and then removing myself from a class. Here's the class I was testing on: http://en.wikipedia.org/wiki/Education_Program:University_of_Michigan/SI_110:_Introduction_to_Information_%28W13%29
Even though I took no other actions between enrolling and removing myself, the following 5 log entries occurred:
18:53, 31 January 2013 Sage Ross (WMF) (talk | contribs) disenrolled from course SI 110: Introduction to Information (W13)

Similar phantom log entries seem to be occurring regularly, and it looks like it's something involving actions one course page generating additional log entries for a different course page.
