Unhandled exception in httppersist.py

[jfcabral]

First of all, thanks for enabling the issue tracker ;)

Now regarding the bug, I'm using version 3.4.1 of the addon, installed on both OpenElec and RaspBMC on my raspberry pi.

Since my pi is used by more than one user, sometimes it is used without the Plex Media Server being online. Therefore I have noticed that in the xbmc log file, that this is printed every 1-3 seconds since the service starts (while having the Plex Media Server offline), resulting in a huge spam:

Seems to be an unhandled exception? Maybe there should be a timer between retries in order to avoid such spam? What do you think=
