System Information
Windows 7, NVidia GTX 560 TI

Blender Version
Broken: 2.70

Short description of error
I opened up my scene, it was in Object mode at the time, so I selected the hand because I wanted to sculpt it to make it look better and more life like, so I went to Sculpt mode and activated dynamic topology.
I then selected the clay strips tool, I lowered the strength of the brush quite low so that it would not affect the shape to much nut instead increase the poly count a little bit so that the smooth tool would work a little bit better, then I held down shift to try and smooth it and I noticed nothing was happening so I went back to the clay strips tool amped up the strength and still nothing happened, however I noticed while I was dragging the brush over the mesh that in some parts of the mesh, it was being affected but it looks like really horrible deformation of the geometry (it looks really spikey and rough instead of really smooth), please can anyone help me, I initially thought that the Remesh modifier was to blame so I just stopped using it but know it is happening with meshes that have not been through the Remesh modifier. It is like I have masked the whole mesh apart from some areas, and the areas that are being affected, the behaviour of the clay strips tool is not correct with what I know it should be.

Exact steps for others to reproduce the error
Open up .blend file
Select hand L
Move to Sculpt mode
Select Clay Strips tool
Increase the strength to 50%
Change the falloff to the Square Falloff
Try Sculpting on the hand (Nothing happens, but in some areas something does happen but not what should happen)

This is yet another scaling issue. The problem goes away if you apply the scale before entering sculpt mode.

This fixed the issue for me in the attached .blend:

Object mode, Apply scale (ctrl-A)
Edit mode, select all (A), recalculate normals (ctrl-N)

Sculpt mode works as expected.

This fixed the issue for me in the attached .blend: Object mode, Apply scale (ctrl-A) Edit mode, select all (A), recalculate normals (ctrl-N) - > Sculpt mode works as expected.

Thanks for the quick response, its much appreciated, I have been having this issue for ages know and everytime I had to retopologise the mesh each time this happened, initially I thought It was my .blend files becoming corrupt over time when I just left them, but know I know that is not the case, at least I now know how to solve the problem.
