Steven (PyCall author) posted on this a few days ago.
The bug has been fixed, you just need to
Pkg.checkout("PyCall")
which will get the latest version of the code from master.
Note, though, that even with this fixed, I'm having some problems with
plotting in the IJulia notebook (dead kernels), though things work just
fine from the REPL.
