Do you mean that you applied the patch to the Hardy version of pycrypto? Did you also fix it in Debian? Or did upstream pycrypto maintainer fix it and I didn't notice?

Thanks!

Also, shouldn't this be marked "fixed" instead of "invalid"?

Regards,

Zooko

re hardy: I don't care that much; I accidentally opened the task for hardy.

So, just for the record, if someone is using pycrypto on hardy, are they susceptible to this bug? I'm not sure whether the fix made it into hardy or not.
