Nah, here we're _inside_ decode_handle(), where h = 0 according to the
previous backtrace sent on the list.

So, hrm, there's something fishy in there.

Jim, could you try with just

DBG (DBG_ERR, "decode_handle: w->status: %d, h: %d, num_handles: %d\n",
     w->status, h, num_handles);

This way we should get an idea of what's going on...

JB.
