1493763 - Windows "Not Responding" for many minutes after startup with lightning, plus high memory, caused by invalid rrule

Status: RESOLVED DUPLICATE of bug 978060

(Calendar :: Internal Components, defect)

Description

[Wayne Mery (:wsmwk)]

Daily hangs on startup for many minutes (up to 20) or when I change the view (3-4 minutes) at CPU usage 13%. 

Makemyday kindly looked at my data. He writes ...
parsers could not handle invalid rrule
 RRULE:FREQ=DAILY;UNTIL=20141230T225959Z;COUNT=52;BYDAY=1TU,3TU,5TU
per RfC5545 section 3.3.10 [1]:
  "The BYDAY rule part MUST NOT be specified with a numeric value when the 
   FREQ rule part is not set to MONTHLY or YEARLY."
FREQ should have been MONTHLY instead here. This is a problem for both libical and icaljs, so there's no other workaround available then removing the item from the calendar storage. 

In console, after first extremely long wait (minutes), I see

Comment 2

Probably not happening as much if at all since 78.x?

I have no reason to believe it is gone. But it could be.

Needs to be retested
