Thanks, I tested this patch and it now makes sense of the affected invite.

I've also reported it upstream to lfx.dev, but I'm not clear if the ICS 
attachment is written by them or originated from Zoom. I suppose if all 
Zoom invites caused Alpine to crash someone else would have noticed by 
now.

Either way, I think that's the end of the matter for me. Thanks for 
fixing!
