%%%--- Operating System, Graphics card ---
Ubuntu 12.10 amd64
NVIDIA GeForce GTS 450 (304.51 driver)

- Blender version with error, and version that worked ---

Version with error: r54602
Version that worked: ???

- Short description of error ---

When sculpting in dynamic topology mode, brushing over masked areas with Collapse Short Edges results in loss of detail in those areas.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Load default blender scene and select default cube
Add and apply level 6 subsurf modifier (to get nice initial definition)
Enter sculpt mode
Using Mask brush, mask out an area of the mesh
Enable Dynamic Topology and Collapse Short Edges. Default detail level should be at 30.
Make sure that your zoom level is set so that one polygon of the mesh is less than 30 pixels (normally this would be the case after 6 level subsurf and zooming so that the mesh almost fills the screen).
Select Draw brush and set brush strength to 0 (the value doesn't matter, 0 just does not displace geometry).
Stroke over masked area
Observe how masked geometry gets rearranged according to Collapse Short Edges
