TypeError: Cannot convert AsyncDisk to diskimpl.PartitionAsyncDisk

I'm getting a cython TypeError when running the verifier.

$ python2 verify.py
Verifying WAL Layer.........................................0.228846 seconds

Failure.

I am using cython 0.25.2:

$ python2 -c "from Cython.Compiler.Version import version; print version"
0.25.2

Hi cdetrio,

There are some issues with running the verification on the compiled Cython code. We use Cython only for obtaining a binary for execution, not for verification.

Try make clean followed by make verify and see if that fixes your problem.
