The printed info above is from my Windows laptop a long time ago, when running a python version of SyncY v2.x. I got the same errors nowdays, still.

Similar problems when using Blowfish cipher. However the ARC4 is good. SyncY version is Python v2.5.3

I fix it from this : https://bugs.launchpad.net/pycrypto/+bug/1018283 on syncy.py line 1604: add 16bytes sth, Modif　like this:
return AES.new(key.ljust(32, '.')[0:32], AES.MODE_CFB,'0123456789012345',segment_size=8)
