This is neither a bug in pdfpages nor in pdfcrypt. I can
reproduce the error with just low-level pdftex primitives.

\pdfcrypt owner {}
\immediate \pdfximage width 100mm {yp_super_investments.pdf}
%\immediate \pdfximage width 100mm {yp_super_rollover.pdf}

I suppose there is a bug in your perl script. The above example file
creates a well formed PDF document, if `yp_super_rollover.pdf'
is inserted. But any PDF viewer crashes if `yp_super_investments.pdf'
is inserted. So it seem to be the conversion from .._rollover.pdf
to .._investments.pdf which is buggy.
