I used to have TSVN installed, but don't recall if I ever ran the HEK while it was installed so I can't say if I ever had a problem with it.

I'm pretty sure the problem stems from how I package the tools, but thats the only solution I can offer at this time. If it was a more widespread problem I would have tried harder for a solution but its not something that pressing to me as there are work arounds.
