"Python function terminated unexpectedly" on ePub to PDF conversion

[zunga]

I've been getting these annoying errors every now and then with many different ePub files whenever I try to convert them to PDF. Conversion process starts normally but gives this error message right when it steps from 99% to 100%. I tried reinstalling and wiping all files inside calibre's book library folder with no sucess. No matter what I do it will always show the error message below after reaching 100%:

"Python function terminated unexpectedly
PDF Output failed, see log for details (Error Code: 1)"

This happens even with ePub files I had successfuly converted in the past with older versions of calibre.

Full message copied from log:

Python function terminated unexpectedly
PDF Output failed, see log for details (Error Code: 1)

@zunga

There have been some changes in convert to PDF recently - have a look in the Change Log for details

If you want to lodge a defect report then its best to do that here Calibre Bugs

- thanks Doc.

Thanks for the reply.

That being said, I think the easiest solution would be to step back a few versions for two or three months. Do you know where I can find the older releases?

Same place you got the current version
Look for the small words "Previous releases here"
(just under the 'Donate' Payment cards)

Actually the best solution is to work with Kovid by opening a bug report; normally he is very quick in resolving these issues and a fix will be in the next release.

do both - go back and find a version that works, and post a bug report

Kovid posted a new 9.22 within 12 hours of me reporting a conversion bug last friday evening - my time, afternoon his time.

I did try some epub to PDF conversions and had no issue, so it might be something local to your setup.

Thanks a lot guys, I'll do it.

So I rolled calibre back to version 0.9.12 and everything is working again!
