371133 - Extra linebreak in ics/webdav publishing removes SUMMARY in Apple iCal

Status: RESOLVED DUPLICATE of bug 324198

(Calendar :: Provider: ICS/WebDAV, defect)

Description

[Rinke Hoekstra]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-GB; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1
Build Identifier: Lightning 0.3.1 build 2007021405

The ics files created by lighting have an extra linebreak between the ID and SUMMARY content lines. This causes the Apple iCal ics import/subscription mechanism to interpret the linebreaks as '\n\n', which results in the ID field and SUMMARY field being concatenated. The effect for Apple iCal subscribers to Lightning-published calendars is that the VEVENTs don't have a title anymore.

An example, Lightning created the following lines:
UID:
 D31D4389-2F7D-48C1-98B7-F0D395D60037-1C81897E-88A5-41AA-A6A6-B69760851175
 
SUMMARY:Juridisch Kennismanagement

Which are interpreted by Apple iCal as:
UID:D31D4389-2F7D-48C1-98B7-F0D395D60037-1C81897E-88A5-41AA-A6A6-B697608
 51175\n\nSUMMARY:Juridisch Kennismanagement

Perhaps the way Apple iCal parses the ics file is not standards-compliant, but the extra line seems to be redundant, and can be left out.

Reproducible: Always

Steps to Reproduce:
1. Create a calendar using Lightning
2. Publish it to a WebDAV thingy
3. Subscribe to the calendar using Apple iCal
Actual Results:  
The titles of the events in the created calendar do not show up in iCal. Having a look in the cache (e.g. in ~/Library/Application\ Support/iCal) shows the way iCal has parsed the calendar files

Expected Results:  
Wel... show the titles of the events ;)

Lightning doesn't create that kind of long UIDs itself. But it has some problems when reading and writing such UIDs from foreign source, see Bug 324198. Duplicate?

Tested in iCal V. 2.0.4, this issue is indeed caused by the problem in bug 324198.

Marking this as a dupe of 324198.
