      I tracked down the entry in the source database (from the Moodle that created the backup file), it is:

         id    |    time    | userid |      ip      | course | module |  cmid  |   action    |                    url                     |  info
       7525025 | 1378796360 |  25675 | |   8223 | forum  | 286790 | update post | discuss.php?d=107533#p183098&parent=183098 | 183098

      This is represented in the backup file like this:

        <log id="7525025">
          <action>update post</action>

      I spent some time trying to debug it, but didn't find a solution. Perhaps someone more familiar with the forum backup / restore code should look at it.
