 the line breaks stay correct, BUT enabling the HTTP debugging in iCal I
 think the even is not even read again. I can see the PUT Request, but then
 just the ETag is compared and the event is not reread from the server.

 New description:

 (sorry for the spam, my first attempt at replying was wrong so I had to
 roll the ticket back)

 I'm not able to reproduce this using current trunk (r6917), iCal (Version
 4.0.4 (1395) in Mac OS X 10.6.5, and iOS 4.2.1. Creating and event with
 iCal and iOS both seem to produce the same correct behavior, and I'm also
 able to edit the events later without seeing any additional unexpected
 line breaks.

 A multi-line description is displayed as followed by CalDAVClientLibrary:

 {{{DESCRIPTION:First line\nSecond line\nThird line added later.}}}

 Looking in the DB, it also appears correct:

 {{{
 caldav=# select icalendar_text from calendar_object;
                          icalendar_text

 Also, I just learned that this exact issue was encountered at CalConnect
 last week with an Android client. Turned out they were not handling "\n"
 properly on their side. They were expecting an uppercase N, not lowercase.
