Comment 19 for bug 215614

The problem seems to revolve around the calendar part, and not the mail. From what I gather, when the calender is refreshing, that is when the locking occurs. I also had the same issue when I subscribed to my gmail calendar, and it went away when i removed the subscription.

There is also a bug not allowing the user to store the calendar locally ("folder not found" error), which might solve the issue entirely.

It is almost unusable for me; I have to restart about every ten minutes.
