Cannot switch between pattern pieces on latest develop (osx)

[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

See video for screen cap: https://youtu.be/AZHsActXrQU (file from video is attached)

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

OS: Mac OS X 10.10.4

Works only for new file. If open file all works fine.
