Comment 1 Richard W.M. Jones 2011-03-18 18:50:56 UTC 
This appears to have fixed itself magically between 1.8.1
and 1.8.2.  Since I'm not sure what commit fixed it, I'm
leaving this bug open out of caution.
Comment 2 Richard W.M. Jones 2011-04-12 17:11:53 UTC 
This is not happening with 1.9.18.  Also I checked with
valgrind, and it cannot find anything.
