PHP error when using Limit Section Entries

Hello,

This is a bit of a hack/patch as I am not completely sure what is going on. But if a section has limited entries with the Limit Section Entries plugin, or is using the deprecated Static Section, upon saving an entry the following PHP error is thrown:

    Fatal error: Call to a member function get() on a non-object in /extensions/tracker/lib/class.tracker.php on line 267


I have added a work around to which prevents the error from being thrown. I believe leaving the nicest logs in the tracker, therefore could be improved.

Thanks,
Ross
