Sketch and Retro both crash if the user rotates the device after selecting "Take Photo".
To reproduce in Sketch:
1. Start Sketch
2. Position device in Portrait
3. Tap "Take photo"
4. Position device in Landscape
5. Take photo
6. Tap "OK"
7. "The application "XnSketch" (process com.xnview.xnRetro) has stopped unexpectedly. Please try again"... with the "force close" button.
Same behavior in Retro.
Summary: Force close occurs if the photo is not taken in the orientation of the app.
