(Get the code!)
I see a similar problem on a friend's computer, but in this case she's using an https connection to the webdav server and a secure SSL connection to the POP3 server (not IMAP). As Frank said, it seems to happen when she changes the calendar during a timed mail check. The timed mail checks happen every five minutes so she sees this problem at least once per day. In this case it doesn't matter if it's a meeting invite (she doesn't send or receive them).
The CPU was at 100% and I had to kill Thunderbird. Before I killed it I checked the current internet connections using Process Explorer. Thunderbird had open connections to both the POP3 server and the webdav server. The connections were stuck in the "Close_Waiting" state. Both servers are at FastMail.
This is on a single core 1.0 GHz CPU (WinXP), a high-speed internet connection, and the ICS file is over 100 KB. I forgot to check the Error Console but it's too late now because she wasn't happy so I switched her calendar to a local ICS file. She's using the 0.7 release version of Lightning and Thunderbird 2.0.0.9.
