Problem opening epubs with embedded fonts in latest nightlies

[sladflob]

Hi, I just tried opening some books that contain embedded fonts in a recent nightly build (v2020.06-45) and get a segmentation fault. Here's the error from the crashlog:

07/19/20-14:03:06 INFO  RD loaded plugin texteditor at plugins/texteditor.koplugin
07/19/20-14:03:06 INFO  RD loaded plugin timesync at plugins/timesync.koplugin
07/19/20-14:03:06 INFO  RD loaded plugin wallabag at plugins/wallabag.koplugin
07/19/20-14:03:06 INFO  RD loaded plugin zsync at plugins/zsync.koplugin
CRE: document loaded, but styles re-init needed (cause: embedded fonts)
CRE: styles re-init needed after load, re-rendering
Segmentation fault
!!!!
Uh oh, something went awry... (Crash n°1: 07/19/20 @ 14:03:07)

I tried updating to the latest nightly (v2020.06-58) and it still has the same problem. If I run the epub through Calibre and remove the embedded font it works fine. I downgraded to the latest release and it also loads the epub with the embedded fonts fine. Has a recent change broken something?

BTW, what's the best place to report these kinds of problems in nightlies? Here or on github somewhere? Is there any more info I can provide?

It seems so as you cannot reproduce on previous versions

You can provide the epub with embedded fonts. If it is copyrighted material you'll need to scramble it first using https://www.mobileread.com/forums/sh...=epub+scramble

OK thanks, scrambled book and added it to the issue #6394 that I just raised
