I described the issue earlier on in this thread, but basically...

Bodhi's PackageUpdate.assign_id method is a little crazy, mainly to hack
around SQLObject shortcomings (like not storing miliseconds in
datetime columns).  This method apparently relied on the
PackageUpdate.date_pushed field *not* getting updated when an update
goes from testing->stable in order to determine the last ID assigned,
since we assign update ID's right when updates hit testing (which I am
thinking about changing in the next major release).  I recently made a
subtle change that updates this date_pushed timestamp when a testing
update hits stable, and thus broke the id assignment algorithm.  Sadly,
the test suite did not initially catch this issue, but I have since
added a test to reproduce the issue, and have written code to detect
these duplicates and re-assign their IDs.
