----------------------------------
Hi Vivek,
This morning we found that there was a little disparity between 0.9 and trunk
regarding this fix. Yes, you would still have this problem in 0.9, but with the
latest checkin, the problem should have been addressed. Let me know if you
found that this is not the case.
