Calibre 7.44 crashing while converting

[DeadMan]

Crashing while converting LIT to RTF.
Also crashes when convertng to MOBI, ZIP, ePub, FB2 playing with the below options.

Converting an epub also crashes and leaves calibre-parallel.exe process stuck in memory. This doesn't happen with the others above.

I have managed to crash it more than 20 times now while turning on/off some of the heuristic options. Since I mostly convert to RTF first for editing purposes, this is what I played with the most.

If it decides to convert with one option suddenly, I can turn on or off one of the others and it will crash.

These are the heuristic 3 options I played with the most, and will consistantly crash Calibre while turning them on or off:
- Ensure scene breaks are consistently formatted
- Remove unnecessary hyphens
- Italicize common words and patterns

My system:
Win7 Ultimate x64, 8 gig mem.

(Don't know if this helps you)

On another note:
When the conversion does complete, something is funny with it after I open it in Atlantis.
It will normally load just fine, showing the Times New Roman font as usual. But now, it loads as shown (in the pictures), and for the life of me can't figure out why. No matter what I do to the font or structure, it will not change how the font is displayed. Maybe this is a handling bug in Atlantis, but I have not seen this happen before.

If I load the rtf into Word, it will usually display fine. I can just resave from word, and reload it into Atlantis and it displays and works fine again.

Twice now it has displayed any words that ends with an 's, 'd, 'll, etc. with a japanese type of font. Meaning, it will replace only the 's, etc with the japanese style, not the word itself. I cannot reproduce this effect at all.

Thanks for looking.

Are you saying it crashes only if you use heuristics and not otherwise?

Yes.

It seems, after I restart and do a conversion and do not touch any of the heuristic options (Calibre remembers the selections prior to the crash), it will do the conversion. Only after turning an option on or off it will cause the crash.

And you are doing nothing other than converting, for example, you are not downloading metadata?

No, just starting up and selecting a book for conversion. I don't alter any other options within the conversion options since I have had them set to the way I want for quite some time.

I was just going to try the scene break options after installing the update this morning.

That's just weird. Can you run calibre in debug mode and post the debug log (click the arrow next to preferences).

Here you go. Clicked the Italicize option off, since it was on after starting, to generate the crash. This is the complete log.

Try this build:

http://calibre-ebook.com/downloads/b...bre-0.7.44.msi

You will have to uninstall and then install this build. Uninstalling will not affect your library/settings

Converting LIT to RTF now seems to work again, except for the formatting problems when opening in Atlantis.

Converting an ePub to RTF still crashes though.

If I use the same options to convert the ePub to an RTF, that I used for the LIT to RTF, it did not crash. Only after turning the usual hueristic options on/off did it crash.

Can you attach this epub to this ticket: http://bugs.calibre-ebook.com/ticket/8762

Is your calibre interface in english or some other language?

[DeadMan]

It is English, set to English in prefs.

[kovidgoyal]

Then I'm afraid I have absolutely no clue what could be causing your crashes. Anything else you can think of that might be unusual in your calibre install or settings?

[DeadMan]

Not a thing. It's pretty much the default install. No extra plugins added or anything like that.

Only thing I did recently was add the tweak categories_collapse_more_than = 0 a few versions back when it started sorting authors strangely after one of the new updates. Not sure if thats the one or not, but something like that. I'd have to go back through the forum to see what it was exactly.

Some time ago, about July, I disabled a bunch of device drivers - only leaving my Jetbook one active - to see if that would spead up startup times. Then in Sept, I moved everything to my new PC, so load times became less important and I haven't been concerned about it.

Otherwise, I install the weekly updates as they come out and leave it at that.

I will install 7.43 again to see what happens.

Thanks for looking into it Kovid.
