anki can't download any deck

[Guybrush88]

Binary package hint: anki

each time i want to download a deck i can't because anki says that it is corrupted or invalid, but it says so even when i download decks that i downloaded correctly a few months ago. i use the latest ubuntu with everything up-to-date.

another user who uses anki got the same error

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[hackel (hackel)]

Confirmed on Anki 1.0.1-1. Fixed by upgrading to latest version (1.2.8-1) from ankisrs.net. This version is included in Oneric, but have not upgraded yet, so I cannot test if the problem persists there.

[François Marier (fmarier)]

Fixed in Ubuntu 12.04.
