Initialization Error

I am currently experiencing an error when using pyjulia:

>>> import julia
>>> j = julia.Julia()
WARNING: redefining constant JULIA_HOME
InitError(:PyCall,PyError (:PyImport_ImportModule) <type 'exceptions.SystemError'>
SystemError('dynamic module not initialized properly',)

I did successfully initialized pyjulia before, but somehow it's not working for me now, probably because I updated my julia packages recently.
I tried to remove PyCall and reinstall it, and remove PyJulia and reinstall it, but that didn't work for me.
Thanks.

I have the same issue on Julia 0.5.2. It did work before on Julia 0.5.0.

I think I managed to resolve it by deleting an entire pyjulia folder in .julia/lib.
