[Bf-committers] Modifier Crash-

[Campbell Barton]

Hi Danial, I found a bug with the modifiers-

If your rather I use Bugtracker or mail you personally, ley me know.

To reproduce

    * Add a sphere
    * Add a num,ber of materials (I used 6)
    * Decimate the mesh 0.5
    * Apply decimation
    * ** Note derivedMesh not updated and mesh appiers invisible until
      you toggle edit mode.
    * ** Note Material slots are all set blank
    * Go into Editing panel and try remove the 6th material -> Crash


Heres the Backtrace
