Thanks for the suggestion.

My repo is at revision 116, and the highest revision in the latest
"working" dump is 110. I tried dumping rev 110:111 but it failed. As
did 109:110, and almost any of the other combos I tried. Stangely,
dumping incrementally from 95:96 works, though 94:95 fails, just like
96:97 - even dumping from revision 1:2 fails...

The errors thrown are these (in random order):

svn: Invalid diff stream: insn 0 cannot be decoded

svn: Invalid diff stream: insn 0 overflows the target view

svn: Unexpected end of svndiff input

I guess I'll load the backup at revision 110, and try and commit my
local copy into that... I don't have enough time to spend fixing the
borked repo right now. :-)

The repository has survived upgrading the server OS from Mandrake 9.2
to 10.1, including the trouble with changing from the old subversion
RPMs from Ben Resers urpmi-site to the new included-with-Mandrake
subversion packages, and also upgrading the Berkeley DB libs from v.
4.1 to 4.2, so I guess it was bound to go wrong at some point. ;-)

Thanks again.
