Never got any error in any way, except by repeating the svnsync from the master.

I think it's a bug, too.
We (elego) have seen this svnsync checksum error at a customer site, too.
Never figured out how to reproduce it.

I have a supposed "good" copy of the slave repo, at rev 4050... which will fail every time at 4061 (or something like that)... The only explanation I can find is a md5sum collision going undetected, and then some larger operation has an md5sum which fails as a result. I know it's astronomically impossible, but I can't come up with any other explanation.

So you can reproduce it reliably? That's very interesting.
I'd like to try to debug this. If it's possible to arrange access to
your repository data please contact me off-list. Thanks.
