It looks like the client (Fedora 16?) is sending an invalid packet.
I would have expected the packet to be rejected before the size check,
but maybe you just got (un)lucky.

Are you sure they are all the same versions, sounds like they are not.

First, v0.3 is unsupported and broken/insecure. Worst thing is that this
is 0.3.6, so it's not even the latest from the old (and no longer
supported) v0.3 branch. Do not use.

Second, it looks to me like your Fedora box is not running 0.7.8, maybe
some older version too.

So, the simple answer is: run supported versions and everything should
work fine, until then, I can't help you, sorry.
