Sync does not recover on "connection reset by peer"

Hi there,

first of all: Thanks a lot for that great piece of software you've created!

Problem description and steps to reproduce:

• sync upload a lot of data (for several hours or days)
• wait for a "connection reset by peer" error. This will happen reliably after a while.

Expected behaviour:

auto-recover connection

Real behaviour:

The sync crashes fatal with a message like this:
