Why does Mail.app keep segfaulting in this method call:

[MetadataManager getAllCalendarStoreData]

I’ve turned off data detectors, rebuilt my iCal database, rebuilt my Mail indexes, and pretty much everything else I can think of, and it still crashes anywhere between 2 minutes and one hour after I start it up.

Mind you, I have no idea why your email client is importing all of my calendars in the first place…

[Update: various forum posts suggest that this is tied to Leopard’s merger of iCal to-do list functionality into Mail, which works by syncing your local to-do lists up with your IMAP server. Except that I don’t use iCal for to-do lists, and wouldn’t want them on my mail servers if I did. So, a feature I’ve never used that does something I don’t want has inexplicably started causing my email to crash at random intervals, and since the bug has been around since at least 10.5.2, it’s unlikely to be fixed deliberately. One can only hope that there’s enough mail-related cleanup in Snow Leopard that it starts working there…]
