I first noticed this problem in Zsh 5.0.0, but I have just built Zsh 5.0.2
from scratch and every time I call exec zsh from another shell (e.g. tcsh).
My $PATH variable ends up with two additional paths, one pointing to
Keberos and another one pointing to a version of Qt.

I don't have anything in my .zprofile nor on my .zshrc.

Why are these paths added to $PATH? Any pointers on what I can look at?

Thanks,

James
