-----------------------------------------------
@Alex
The hudson has taken up the patch and it is available in the versions where
ever the patch has gone in.
There are some test case failures caused in the build due to which the hudson
says it has failed in creating a build. May be you can just cross check from
the build report whether your patch has caused any failures.
