If you can demonstrate a reproducible method to make this happen, they'd be glad to fix it -- and quickly, I suppose.
The immediate upload and almost simultaneous download happened every time I repaired the faulty queue.dat (twice Qfix and a -delete x inbetween) ...
Is that reproducible enough ?
I wouldn't have posted it if I hadn't seen it more than once; I 'm a lifelong technician/electronics pro, I know better than to report a single event as a bug.# SMP Client ##################################################################

ALSO: the 4 minute delay whilst running -delete (in the v6 client anyway) is also reproducible; it did it every time too and from the 2nd time on I timed it (happened 4 times in total since the end of April 2008).
It is known that the client has a 4 minute wait after every it finishes (100%) before downloading a new WU ...
