Starting Marvin XD gives an error: Unhandled exception #33

Stats: Marvin 2.6.5 iPod touch 4th gen (iOS 6.1.5) Windows 7, 64-bit calibre 1.23.0 Marvin XD 1.1.1 iOS reader applications 1.3.4 iTunes 11.1.4.62

When I connect my iPod to calibre, it shows up in the menu correctly, and the red Marvin icon works. However, when I click on Marvin XD, it gives me an error while identifying the books in the Marvin library:

The iPod then disconnects from calibre, and a status bar labeled "Identifying 76 books in Marvin library" stays on the screen at 100%. The Marvin XD icon is grayed out, and says "Marvin not connected" (even though the ipod touch is still connected to the laptop).

I have never seen this error before, but it appears from the traceback that the error is occurring inside an iTunes code library.

A couple of questions: Have you recently updated iTunes? Has the plugin ever worked for you? If so, what has changed on your system since it last worked?

I would suggest removing and reinstalling iTunes as a first step.

  1. I updated iTunes to the latest version a few days ago because it kept crashing on my laptop.
  2. I just started using calibre and Marvin, and it gives me that error every time I click on Marvin XD.

I'll try uninstalling/reinstalling iTunes and post the results after I do.

Take a look at this post, it might be related.

Got Marvin XD working.

I reinstalled iTunes, but it still gave me the same error. Also, when I started calibre and then connected my ipod, iTunes started at the same time, and calibre gave me a different error. (Unfortunately, I closed it before I thought to copy the traceback...)

I thought the error might have to do with iTunes sync, so I disabled it, restarted my computer (just in case), and made sure iTunes didn't start when I connected my iPod.

I tried starting Marvin XD again, and this time it didn't give me any errors.

Thanks for the followup. I will add the information about disabling automatic syncing to the plugin thread.

I will close this issue as it seems to be resolved.
