Error when importing MobiPocket files.

mbovenka · 08-03-2008, 03:03 PM

When trying to import the Blackmask DVD (some 10.000 classics in Mobi format) Calibre 0.4.80 crashes with the following error:

C:\Program Files\calibre>calibredb add -r "z:\Blackmask DVD\mobimax"
Traceback (most recent call last):
File "cli.py", line 430, in <module>
File "cli.py", line 427, in main

File "struct.pyo", line 87, in unpack
struct.error: unpack requires a string argument of length 20

This is when running calibredb by hand, but the GUI pops up the same message when I do it. At first I thought it was stumbling on DRMed Mobi's (when trying it on some other ebooks), but these are all non-DRMed files.

Any idea what the problem might be?

Attach one of the problem mobi files (or send it to me by email)

This is one Calibre chokes on. Mobipocket Reader, uBook & FBReader open it without problems, although the formatting is an ungodly mess.

Will be fixed in next release.

0.4.82 no longer gives an error with that one, so that's fixed!

But it now gives the following error on the attached Mobi file (and others that I haven't yet identified):

235802126

I've removed the attachments as those book are not legally allowed to be posted here. If you need to post them someplace, please go to the Calibre site and open tickets so you can attach them.
