Reproducible: Sometimes

Steps to Reproduce:
1.happens very very often at startup

I restart 3 or more times thunderbird to make it not consume 100% of my CPU !!!
How could I've got more information
Actual Results:
lightning + thunderbird hangs
I'm _not_ using cached calendar
the CPU is 100% used
I noticed that when it hangs and I closed thunderbird its pop-up a message, "a security connection has not been closed properly"
It's hang as soon as lightning fetch calendar the cpu reach 100% and then hangs
until it has passed all calendars
What is stranged is that lightning fetch calendars disabled even when alarm are not to bee shown on this calendars

lightning + thunderbird hangs during 5mn at least with 23 caldav calendars

Expected Results:
lightning works properly as soon as I launch it

I've not real idea of what happens !!
I'm not sure that the error log is about that
