This line is in /var/svn/testrepo/db/revs/0/0 file.
It is parsed correctly.

I don't know the internal mechanism of subversion, so I don't know
what is this second text representation.
I guess it is generated for the committing (next) revision.
The issue coming (I think) from this function: svn_fsfs__write_noderev
which is called from svn_fs_fs__put_node_revision
