ValueError trying to connect to agent

[thorstenkampe]

I get the following exception (see below) from agent.Agent() under Python 2.7.10 32-bit when PuTTY Agent is running. The error does not occur when PuTTY Agent is not running:

Traceback (most recent call last):

I'm getting the same exception. Python 2.7.10 64 bit, paramiko 1.16.0, Windows 10 64 bit.

I fixed it for now by downgrading to paramiko 1.15.0

This might be the same as #613, although it seemed that the problem was only related to 32-bit Python.

What @hobbsd said, this sounds a lot like #613 and may otherwise be fixed by the patch addressing that. Will be cutting 1.16.1 pretty soon with that fix in it. Please follow #613 / #619 and reopen this if the release doesn't fix it for you, @thorstenkampe - thanks!
