Subject: Re: Error invoking PDFTK when running from TextMate

I had the same problem.

Turns out it was the security settings on the pdf I was attempting to 
read.

I was getting the exact same error, so I resaved the pdf with NO 
security settings and the problem went away!!!

I think you can supply the password to pdftk as well.
