Is that Subversion that is asserting? It would help if you showed the
exact error or assertion. If moved_to is missing Subversion usually
falls back to copy and delete:

$ svnadmin create repo
$ svn import -mm repo/format file://`pwd`/repo/A/f
$ svn co file://`pwd`/repo wc
$ svn wc/A wc/B
$ svn mv wc/B/f wc/B/g

$ svn st wc
D wc/A
> moved to wc/B
D wc/A/f
A + wc/B
> moved from wc/A
D + wc/B/f
> moved to wc/B/g
A + wc/B/g
> moved from wc/B/f

$ sqlite3 wc/.svn/wc.db "update nodes set moved_to = null"
$ svn st wc
D wc/A
D wc/A/f
A + wc/B
D + wc/B/f
A + wc/B/g
