Calibre hangs when sending to Kobo Glo HD

I had a pdf file that took me 300 minutes to convert to epub, using calibre.

Now when trying to send the epub file to my device, it eats 100% of the CPU, and the interface hangs. I have waited for more than 30 minutes before killing it.

Sending other epub files works fine, in less than a few seconds.

Would you have an idea of what could be the problem?

Code:
+ ~$ calibre-debug -g caldebug.txt 2>&1

Hard to say without access to the file in question.

Hi kovidgoyal,

Isn't there a way for me to troubleshoot the problem?

For example, why would it depend on the file? Does Calibre do some kind of processing before copying the file? The Kobo Glo HD reads epub, so there is no need for conversion.

While sending, I think that there was also the calibre-parallel process running.

Because I don't have any way to pass you the file, do I? Would an excerpt be useful?

Of course it does processing. Vanilla calibre updates metadata and if you have any of the kobo plugins installed, it could be doing anything from updating metadata to re-formatting on the fly to specialise for the Kobo.

And if you want to send me a file, simply opena bug report and attach it.

As recommended, I opened a new issue.

Thank you.

@Kovid: From the log above, it doesn't look like the send has reached the drivers. They are noisy and you should see a message starting with "KoboTouch" if it has.

I can't see the bug report, so I can't check that.

It was apparently just caused by a bad pdf source document which resulted in an epub with too many image files.

Sorry guys, I forgot to update this thread. Indeed, it was because of too many files in the outputted epub (more than 200 000). Once I unchecked the importing of images from the pdf, the conversion took less than 1 minute and sending took less than 5 seconds.

Thanks for your help though!
