Hi Hemant,

I haven't been able to reproduce reliably the issue you reported, but the
above fixes what I *think* to be the issue causing the error print. If you
get a chance, can you do a quick re-test and see if it re-occurs for you.
If not, I'll apply this version - otherwise I might just apply V1, since
the error itself appears harmless, as you say.
