I accidentally found a way to duplicate redstone blocks.
Steps to reproduce
1. Place a redstone block two blocks away from the ground
2. Then place a piston on the ground right below
3. After before the piston can extend place any block above it resulting in a duplication of the redstone block.
4. Then update the block that has been pushed up which will then make the block disappear and be replaced by redstone.
I expected the piston to not even extend at all.

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.
BTW: The issue that the piston extends at all is MC-108
After leaving and reentering the world, the second piston is vanished and the redstone blocks is placed in it's original position.
Fake dupe and dupe of MC-631.
Cannot confirm.
When placing two pistons below the redstone block in described manner, the redstone is not duplicated.
