Presenter field containing quotes causes calendar processing failure

[smarquard]

In Opencast 3.x, create an event with a presenter name that includes quotes, e.g.

Some "quoted" presenter

This produces an ical entry with an organizer field like this:

ORGANIZER;CN=Some "quoted" presenter:mailto:Some%20%22quoted%22%[email protected]

Galicaster (latest 2.0.x) fails to process updates from the calendar:

galicaster	2017-09-27 10:34:16,864	ERROR	utils/ical	Error processing ical: 'NoneType' object is not iterable

The scheduled event will therefore not get recorded, nor will any other scheduled events until the event with the unparseable organizer field has past.

Also seen:

galicaster	2017-09-27 10:36:16,846	ERROR	utils/queuethread	'NoneType' object is not iterable

Slightly earlier versions of 2.0.x had a more explicit error which would also cause Galicaster to die:

galicaster 2017-09-27 10:25:02,858 ERROR utils/ical Error processing ical: Content line could not be parsed into parts: 'ORGANIZER;CN=Some "quoted" presenter:Some%20%22quoted%22%[email protected]': 'CN=Some "quoted" presenter' is not a valid parameter string: Some "quoted" presenter

Since the organizer field is not really needed for recording purposes, Galicaster should just ignore it if it's unparseable.

I will take a look to this
