At one point, way back in 0.24 days, I ran into a similar problem, but
short of sending in my repository for manual fixing (which my superiors
wouldn't let me do) I was unable to correct this.
However all was not lost. I *was* able to do an export successfully on
this repository and recover all data OK, and re-import to a newer
version, losing the log information on changes. Well, that is not
exactly correct either as I've kept an old copy around with the old
repository, for the odd time (happened once now in 6 months) that
someone needed to find a reason for a prior change.
I have also come to the conclusion (but do NOT have any proof) that the
corruption occurred because of accessing the repository using both svn
and http simultaneously (and erroneously), perhaps even when doing a
recovery operation. Was involving a directory that was deleted via one
mechanism. Won't do that again needless to say.
The svnadmin dump continued to fail even after catastrophic db recovery
attempts, which is what led me back to the export, which succeeded with
no failures or data loss of any kind.
Don't know if it helps or not....
