I'm New to Cuckoo Sandbox. Why am I getting this error? I don't understand. If there is something wrong, can anyone please explain how to setup Cuckoo Sandbox? My setup works very well before I submit any kind of malicious thing. I've been working on it for the last 5 days.

Thanks !

Yes, that's a bug in 0.5 that has been fixed in 0.5.1-dev. In theory it should only happen with Python 2.6, as we recommend using Python 2.7. You can manually apply this patch to fix it: https://github.com/cuckoobox/cuckoo/commit/a6ae875f437e32d6b0f1af4107c0459f6fa7ecc3
