Is it? Maybe I don't have the deltas inner workings correctly in my
mind, but consider this simple test:

[andreas@pandora x]$ svnadmin create test-repo
[andreas_at_pandora x]$ svn mkdir file://$(pwd)/test-repo/dir1 -m "- created dir 1"

Commit da revisão 1.
[andreas_at_pandora x]$ svn mkdir file://$(pwd)/test-repo/dir2 -m "- created dir 2"

Commit da revisão 2.
[andreas@pandora x]$ echo corrupt > test-repo/db/revs/1
[andreas@pandora x]$ svnadmin verify test-repo/
* Verified revision 0.
svnadmin: Can't set position pointer in file 'test-repo/db/revs/1': Invalid argument

Does the dir2 creation depend on dir1? If yes, then this error is valid.
