As Juan already mentioned, this 1.3.6 for Debian seems to have a big problem.
And as Philip wrote, the problem seems to be a Qt Lib problem.
If I can read correctly, it’s probably because we made a “sudo apt-get upgrade” recently, and that updated our Qt4 Libs to 4.8.6 when insync expects a 4.8.4…
I installed 1.3.5 from here :
Works like a charm… even though I still have the python socket error output upon install.
