Actually, I quickly I found the problem in the mesa state tracker.

But I think the piglit test can be improved a little bit more.

1. In piglit_init() there's two loops which are basically identical, 
except for the last parameter passed to ValidateTexSize().  I think 
you could loop over proxy=true/false and remove the redundant code.

2. Also, the code as-is seems to be missing a glDeleteTextures() call 
at line 448 (using the loop would fix that).

3. You don't actually need to create any texture objects when testing 
proxy textures.
