Hi,

You seems to hit a bug with some internal operation in Mercurial whose 
implementation details were changed in 6.4. I am also a bit puzzled 
about how this would happens as the backup should be done in the same 
directory as the source file, however bug are kind of surprising by nature.

Can you file a bug on https://bz.mercurial-scm.org/ ? I'll have a look.
