Title:
  [SRU] xx-svn-review crashed with ModuleNotFoundError

Status in xxdiff package in Ubuntu:
  Confirmed
Status in xxdiff package in Debian:
  Fix Released

Bug description:
  [ Impact ]

  xx-svn-review will crash immediately on execution with the error:

  $ xx-svn-review
  Traceback (most recent call last):
    File "/usr/bin/xx-svn-review", line 7, in <module>
      from StringIO import StringIO
  ModuleNotFoundError: No module named 'StringIO'

  
  [ Test Plan ]

  
  sudo apt install subversion xxdiff-scripts
  mkdir -p $HOME/.svnrepos/
  svnadmin create ~/.svnrepos/MyRepo
  svn mkdir -m "Create directory structure." \
    file://$HOME/.svnrepos/MyRepo/trunk \
    file://$HOME/.svnrepos/MyRepo/branches \
    file://$HOME/.svnrepos/MyRepo/tags
  mkdir $HOME/test
  cd $HOME/test
  echo "test 1" > testfile
  svn checkout file://$HOME/.svnrepos/MyRepo/trunk ./
  svn add --force ./
  svn commit -m "Initial import."
  svn update
  echo "test 2" > testfile
  xx-svn-diff

  If the package is not fixed it will result in the above error.
  With the fixed package the xx-svn-diff window will be displayed with the diff.

  
  [ Where problems could occur ]

  The only change in the code is in the module import and imports
  StringIO from io for Python3. And as such there is very small chance
  of regression due to this.

  [ Other Info ]

  It has been already fixed in Debian and Oracular will get the fixed
  package via sync.
