Hi guys,

I use Calibre for a while to store my comic books. That means I use three kinf of files : PDF, CBR and CBZ. I never had a problem with that.

I recently upgraded to Ubuntu 13.10, and then imported new comic books into Calibre. From this time, almost all CBR files didn't receive a cover.
I saw that it was supposed to be fixed in 2011, and some workarounds such as "bulk editing" and asking Calibre to get the cover from the file didn't work.

I'm quite stuck... I started downloading covers from Internet, but 1) I don't want to do this by hand for 600+ comic books and 2) a lot of covers aren't even found on the Internet.

I was wondering about a dependency missing, but I got unrar, rar and p7zip-full installed. I didn't change anything in the preferences of Calibre at first, then I went to have a look if some plugin were disabled or whatever, but nothing. By the way, I can perfectly read those files using evince, as usual.

When trying to import manually the cover from file in "simple edit mode", I get the following message : "impossible to read the cover from CBR format".

Of course, I use the latest version of Calibre.
At first, I see two points of difference between "before, CBR cover ok" and "now, CBR cover ko" : I upgraded to Ubuntu 13.10 and in the same time upgraded to the latest Calibre, coming from a version a bit older.

Any idea ?
