Unfortunately (or fortunately should I say) the crash could not be
reproduced today. I have added onpanic. So next time it happens I can
provide the trace.

Last time it happened, it happened on two consecutive attempts, that too
were firsts since the upgrade. So I thought it was easily reproducible.
Not so today.

I will also check possibility of the mobile device being responsible for
this - issues like it receiving a call when file transfer is going on or
something of that sort. On last occasion of crash at least there wasn't
any indication of that kind. Will update if I can reproduce the crash.

Mayuresh.
