Description Chris Jones 2016-07-07 05:46:16 UTC

A crash occurs when a hidden layer is nudged using the arrow keys.  This happens frequently when trying to accurately position a layer while hiding/unhiding it to check if it's in the right position.

Reproducible: Always

Steps to Reproduce:
1.  Create a new image with 2 layers
2.  Select the move tool and select layer 2
3.  Hide layer 2 and press an arrow key

Actual Results:  
Crash.
