Hi Keshava,

If you mean this patch[1], then I tested it against the head and it
didn't fix my problem. I couldn't convince myself that your patch was
supposed to be the whole fix to my problem (since it wasn't mentioned on
this thread) so I didn't reply with my findings. Sorry about that.

Thanks for taking a look,

Alan.
