When I open an iCal invitation (Mail Attachment.ics file) in Mac Mail.app sent to me from someone using Thunderbird, I receive the following error:

iCal Error

The only solution that I've found to date is to save the Mail Attachment.ics file somewhere like the Desktop, open it in a text editor, and delete the blank lines at the beginning and end of the file. This problem appears to only happen when I'm receiving invitations from people using Thunderbird under Windows.

Does anyone know of a better way to solve this problem?
Is this a bug in Apple iCal, or is Thunderbird not meeting the iCal spec?

Configuration Information

OS: Mac OS X 10.6.2
Mail Program: Mac Mail.app ver. 4.2 (1077)
Calendar Program: Mac iCal.app ver 4.0.1 (1374)
