New issue 432: Cannot switch between pattern pieces on latest develop (osx) https://bitbucket.org/valentinateam/valentina/issues/432/cannot-switch-between-pattern-pieces-on

Benjamin Nauck:

  1. Create new pattern file
  2. Press create new pattern piece
  3. Switch back to the first pattern piece
  4. Try to switch to the new piece ← does not switch to new piece

It works fine on v0.4.0.789b (build version c225b96eb4f1) but not on latest develop
