Stefan, any idea of the regression range on this?
Regressed by a change in Thunderbird or Toolkit but not Lightning.

Works: Thunderbird 15.0a1 (20120503134801)
Fails: Thunderbird 15.0a1 (20120504031629)

Attached patch Fix - v1 β€” β€” Splinter Review
I can't say for sure why this patch fixes it, but it does. The original culprit was in calItipUtils, where isInvitation and getInvitedAttendees is checked just like the helper function in calUtils. But, for some reason the helper function in calUtils works!

I've also added calICalendar and calISchedulingSupport to the caldav provider's getInterfaces, in case thats part of the problem.

Just from a gut feeling, I think it might have to do with something in the wake of CPG, that if a QI is done in one compartment, then its not done so for the other one. Since calInstanceOf is also in calUtils.jsm, the patch works.

We might have to ask some xpconnect gurus on that or just hope nothing else breaks, or get rid of calInstanceOf some time.
