Version info:
vince@uranus:/proc$ lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04
vince@uranus:/proc$ uname -a
Linux uranus 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 i686 GNU/Linux
All apache packages: 2.2.14-5ubuntu8.2
Symptoms are that Lightning shows a warning ! against webDAV calendars and the popup message says:
The calendar xxxxx is momentarily not available
The calendar grid shows no events/actions from the webDAV calendars affected.
The Error Console shows the following message for each webDAV calendar:
Warning: There has been an error reading data for calendar: xxxxx. Error code: CAL_UTF8_DECODING_FAILED. Description: An error occured while decoding an iCalendar (ics) file as UTF-8. Check that the file, including symbols and accented letters, is encoded using the UTF-8 character encoding.
When a webDAV .ics calendar file is downloaded via HTTP (Firefox) then viewed (with Notepad on XP client), it appears to contain spurious extra characters at start of file. These are not present in the underlying file as viewed locally on the Apache server machine. gedit on Lucid client baulks at displaying the downloaded file reporting that file appears to contain non-UTF-8 data.
Example:
Underlying file actually starts:

Now, possibly coincidentally, this problem apparently started immediately after I migrated my Apache server system from an old 600MHz Pentium II system to a new dual core Celeron E1200 system. Migration involved little more than moving the system disk from one box to the other.
I see other bugs reported on Apache2 SSL involving corruption some of which refer to a gcc bug affecting code generation for SSE4 cpus so here is cpuinfo for Apache2 server cpu:
