Move of a new folder with renamed file causes "The node was not found"

Hi,
A bit of a corner case but I thought I mention it anyway.

If I move a new folder with a renamed file this causes an error message

I'm stacking move operations, which is probably not wise but a result
of the fact that I'm using a script with some logic to cleanup our
repos.
It looks like the following should reproduce it
svn move A A2
svn mkdir A2/new_folder
svn move A2/file A2/new_folder/file
svn move A2/new_folder/file A2/new_folder/file_new_name
svn move A2/new_folder A2/new_folder_better_name

the last move causes the message like
svn: The node 'A2/new_folder/file' was not found.

So it seems the wrong/old path was used. Somewhere administration was
not correctly updated that the file moved to
A2/new_folder/file_new_name?

Some output with that message

svn status shows stuff has gone missing, I can see several exclamation marks.

I'm using 1.7 dev build revision 961397.

Reproduction script is attached.

Looks like a bug?
