zlib.error: Error -3 while decompressing: invalid block type

[SpongebobSquamirez]

I will get this bug if I highlight more than one card (e.g. by holding shift) and press ctrl+Q. It will usually give this error on the same cards, but sometimes reducing the number of cards selected seems to make it work without giving an error. But after a few tries, it seems like every card I click gives a similar error to this. If I close Anki and reopen it, the cards that were giving errors start working fine, but only if I click on them individually. This basically makes bulk definition adding impossible.

UPDATE: The bug doesn't seem to occur when the number of threads is set to 1. I think it must be related to multi-threading.

I can provide the stardicts I'm using if you like.
