Apparently you cannot edit the dump file with vi.

It is mentioned somewhere in the SVN Book that the dump just looks
like a textual file but actually it is binary. It explicitly does not
recommend editing it in a text editor. (So the problem with checksums
that you are facing is documented).

Can you generate a dump file for a range of revisions? Looking at [1]
you can specify a range of revisions to be dumped by rsvndump tool.

[1] http://rsvndump.sourceforge.net/

Have you tried to compare old and new repository at revision 3186.
E.g. do a checkout and compare whether files and folders all exist and
are the same?

Especially the files and folders touched by r3187.
