"Cannot reshape array" error when deconvolving data from SAA7131 capture card

[ZXByteman]

Hi,

I'm getting error "cannot reshape array" when doing deconvolve process on any data from SAA7131 capture card. I've tried to recover some of my old captures, but no success.

Here is tracelog:

Here is a short VBI sample where error occures.
