I'll try this as soon as I can. I'm not too sure that it will happen as
I think that this is somehow timing related. I suspect that the entry is
disappearing too quickly with 1.4 in some cases but is not a problem
with 1.2. Perhaps some optimization? 

I suggest this because on at least rare occasion, 1.4 did run
successfully, not because I have any clue what was happening under the
covers. 

The systems involved are VERY different as his is a fast 64-bit SMP
while mine is a slow (2 GHz) 32-bit uniprocessor. At least in my case I
typically have only the two internal USB connected devices, neither of
which have drivers. Not sure what USB devices Andriy might have.

I'll let you know the results ASAP, but I in the middle of brining up
DNS anycast for my employer and it is eating all of my free cycles until
it is on-line tomorrow.
