I rely on dayly incremental backups (thanks to the structure of
repositories, these are reasonably efficient). That was useful once in
two years, for a dozen repos, totaling (only) a few thousands commits
with usage patterns that limits the risk of simultaneous update. I think
this one problem was a misguided attempt to undo a commit by messing
directly with the repo. The SMB server itself is a rock-solid,
ECC-everywhere workhorse with an ancient (>10 years old) server software
that we keep for it's excellent reliability and support of MacOS 9 (!)
clients. But I disgress.

I think that I have ruled this out.

That's ruled out. These folders have just been created by the (single)
user with administrative rights. Also the export of a directory goes
smoothly.

Not applicable.
The problem is reproducible on different XP SP3 machines, on different
repos, whenever I select a file and version to restore as described. I
think it is a genuine bug and not related to my config (though I did not
try a clean install in a VM and/or a fresh local repo).
IMHO the error message
Error: Can't move 'C:\rrr\tempfile.tmp' to 'C:\rrr\sss'
with the source a file and the destination an existing directory (the
Export Directory that I just selected) seems a strong indication of some
snafu with parsing the Export Directory when using the User Interface
that I describle.
The only two workarounds that I have found (while still using the
TortoiseSVN GUI) are
- export the directory containing the file (quite bearable, and the
dominant use case);
- manually rename and move the file after the failure.
