The plugin was working last night on my MacBook. I went to produce the log file this morning and did this:
> calibre-customize -b .
> Plugin updated: KyBook3 Sync (1, 0, 1)
Started Calibre and Restart in Debug Mode from the toolbar and got this:

So it seems it is intermittently failing to find urllib3. (Or, possibly, other modules when it fails.) As I said, if I comment out the code and put it back in again the problem goes away and randomly comes back again. Is it a memory issue? As I'm loading quite a lot of Python code to get the Requests module.
