Sunbird fails to import FreeBSD Events ICS

[martinko]

Hello,

I'm not sure whether this is Sunbird fault or ICS is incorrect but after
installing Sunbird 0.3 from ports on FreeBSD and trying to subscribe to
http://www.freebsd.org/events/events.ics I'm getting the following error
message:

There has been an error reading data for calendar: FreeBSD Events. It
has been placed in read-only mode, since changes to this calendar will
likely result in data-loss.  You may change this setting by choosing
'Edit Calendar'.

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.

Please note that long time ago the ICS worked OK with original Mozilla
Calendar add-on.

Regards,

Martin
