I also saw it again about a day ago. This makes it twice within a few weeks 
after upgrading to 7.0-RCX, after running for months without this problem 
before that.

*If* this is indicative that the problem was introcuded, it would then put it 
somewhere in the 2007-09 - 2008-02 neighborhood. Not sure if other people saw 
this prior to 2007-09?
