issue is still seen in the latest 2.0 build.
Comment by Chiyoung Seo [ 25/Jan/12 ]
Recently, we added the fix to this issue. Please reopen this bug when the regression tests reproduces this issue.

Basically could not reproduce the same symptom. Chiyoung looked at the code path and we believed the latest Mike's change must have fixed the issue.
