**System Information**
Windows 8.1 x64
Renderer: GeForce GTX 860M/PCIe/SSE2
**Blender Version**
Broken: 2.73 a1f4821
**Short description of error**
Shrinkwrap projection issue in editmode with Array and Curve modifiers. If you'll disable either of them, projection would work just fine.
**Exact steps for others to reproduce the error**
# Open blend file {F138395}
# Select red squares and enter editmode → Projection issue
# Disable Array or Curve modifier → No projection issue
Use case for this modifier composition — is jewelry design, with this and Duplifaces I can easily make parametric mountings along the ring.
