I have the same problem. svnadmin gives me this error during verify.
svnadmin recover finds no errors.

Error log entries:
<snip>
[error] A failure occurred while driving the update report editor  [500,
#200002]
[error] Can't read length line in file
'/home/subversion/repos/db/revs/47'  [500, #200002]
</snip>

When I try to delete the resources (namely files in /A/c and /A/lib) of
the revision with the error, it seems to work okay, but I have this
entry in the log:
<snip>
[error] Could not DELETE
/source/repos/!svn/wrk/ee9739e9-ecad-1a41-9886-5d65727145a4/A/c.  [409, #0]
[error] Can't DELETE out-of-date resource  [409, #170004]
[error] Item '/A/c' is out of date  [409, #170004]

[error] Can't DELETE out-of-date resource  [409, #170004]
[error] Item '/A/lib' is out of date  [409, #170004]
</snip>


Using 1.2.1 on Fedora Core 1 over https with Apache.

Anybody any clues about this?

Thanks,
Tobias

Can you provide me a copy of the original broken repository (before you tried 
to delete the resources)?  If so, post it to a website and send me the link 
privately, or if it isn't too big, you can send it directly to me.

I've seen this problem a few times, but the root cause has yet to be 
determined.  All of them had an incorrect text representation, but all were 
corrupted in different ways.  At least one of the cases turned out to be due 
to failing hardware.
