Hi the bug is totally reproducible, and it shows every time i do this :
Create a simple box, assign a corona mat and put a bitmap on the diffuse (it works on any channel) then enter the diffuse channel and click on the "show shaded material in viewport" (the button to show the bitmap on the viewport. until here every thing is ok
Now go to the basic options tab, AND put another bitmap on the diffuse (i always pick the bitmaps from my 2 screen, and drag and drop from there to the Capital M of the diffuse channel)replacing the latest one when you do that the material on the viewport wont update to the new one, So You enter to the diffuse channel again and click again on "show shaded material in viewport" and then Corona will crash.
