I can reproduce this on Debian 10, with:

find --version
find (GNU findutils) 4.8.0

Something is definitely going wrong, because after exiting read-write
mode with wdired-finish-edit I end up with *Find* buffer containing
only the header lines:

  /tmp/48659:
  789065 4 drwxr-xr-x 4 rpluim rpluim 4096 May 27 10:57 /tmp/48659/

(but this happens even when the file names involved donʼt have spaces,
so perhaps itʼs a more generic issue).
