File with broken rendering

See the attachment. The summary block isn't rendered, unlike in Chrome.

I note that the bug shows up in Okular under Kubuntu 15.04, so I'm not sure that I've chosen the frontend correctly.
Comment 2 Albert Astals Cid 2015-09-19 16:08:41 UTC
Since i don't have Chrome, please provide a rendering of how you think this should look like.

Adobe reader, either unix or windows, tells:
Cannot extract the embedded font 'Arial,Bold'. Some characters may not display or print correctly.
So I would guess the PDF is not welformed!
Comment 5 Albert Astals Cid 2015-09-21 17:48:45 UTC
Yeah the font stream is empty so the file is defenitely malformed.

Doesn't mean we could try actally rendering it, i thought we had a "if freetype can not open font default to doing font substitution", but it seems not?

Probably a patch to fix this would also fix https://bugs.freedesktop.org/show_bug.cgi?id=92017

Invalidates an embedded font and use an external font

This patch solves it in the splash backend: if it encounters a problem with an embedded font it invalidates it and tries to find a matching external file.

It's probably such easy to solve it in the cairo backend, too.

Pushed Thomas' patch + a leak fix from me.

Reassigning to cairo.
