Comment 70 for bug 633352

I've managed to get something like a functional work-around going for this issue that's been around for a few *years* now.

I've dropped the Google Calendar Provider as completely surpluvous - hoping it would've fixed this issue - it doesn't - and rather making use of Google's native CalDAV protocol.

Find the Calendar ID from the g'cal properties & use https://www.google.com/calendar/dav/$DALID/events , but remove the reminder option, as it's completely broken IMHO.
Allows for bi-directional RW-sync.

I have enough Android devices able to give me those reminders that I might otherwise miss - less distracting than a dialogue I can't dismiss.

This is *such* a long running issue, saying that it's all Google's fault for not being 110% RFC-compliant is a complete cop-out, as I'm able to use other CalDAV clients (such as OS/X native iCal app, iOS) absolutely *fine* with probably the biggest mail & WebDAV servers being used out there atm.
