All text is missing from the output when converted to HTML.

Test case here: http://download.vistair.com/pdf2htmlEX/Page-1fromTCX-B757-AFM-28A_nowatermark.pdf

This file uses type 3 fonts, so you need the --process-type3 option. However seems that something wrong with the fonts, that cairo refuses to convert them.

As an update to this, I pre-processed that page with ghostscript first to embed fonts and clean it up. The test case is here: http://download.vistair.com/pdf2htmlEX/Page-1fromTCX-B757-AFM-28A_nowatermark.processed.pdf

On the original file:

pdf2htmlEX --process-type3 1 Page-1fromTCX-B757-AFM-28A_nowatermark.pdf
Preprocessing: 1/1
Error: Cairo error: invalid matrix (not invertible)

Result = no text on page.

When I try the "cleaned" PDF, I get:

pdf2htmlEX --process-type3 1 Page-1fromTCX-B757-AFM-28A_nowatermark.processed.pdf
Preprocessing: 1/1
zsh: segmentation fault (core dumped)  pdf2htmlEX --process-type3 1 Page-1fromTCX-B757-AFM-28A_nowatermark.processed.pdf

On different Linux system, instead of a core dump, pdf2htmlEX hangs forever.
