Can you add the (redacted) contents of std.ics around line 108 to this report?

Do you see any obvious syntax errors in std.ics?  The file format is here:

Hi, thanks for replying.

Unfortuantely I'm not well versed in iCal format so I don't yhink I'll be able to spot the error.

Here's the relevant line and some edited conext, generated with `cat -nv /home/richis/.local/share/apps/korganizer/std.ics`:

```
   105  BEGIN:VEVENT^M
   106  ORGANIZER:MAILTO:some.one@domain.tld^M
   107  DTSTAMP:20221010T001928Z^M
   108  ATTENDEE;CN='My Boss';RSVP=FALSE;PARTSTAT=NEEDS-ACTION;^M
   109   ROLE=REQ-PARTICIPANT;CUTYPE=INDIVIDUAL;X-UID=69899904:mailto:^M
   110   my.boss@domain.tld^M
   111  ATTENDEE;CN=Me;RSVP=FALSE;PARTSTAT=ACCEPTED;^M
   112   ROLE=REQ-PARTICIPANT;CUTYPE=INDIVIDUAL;X-UID=82753200:mailto:^M
   113   me@domain.tld^M
```

If you or someone else knows an ical validator (preferably a local CLI or GUI app, not a web service or website for privacy reasons) I'm more than willing to install and try it.

Thanks again!

Same problem here, Debian Testing, korganizer, akonadi 22.08.0. Events are missing in my calendar and i get the same errors on the console.

It seems to be related to a bug in libical3.

https://github.com/libical/libical/issues/610

After downgrading libical3 from 3.0.15 to 3.0.14 all events are here again and the errors are gone.

Comment 4 Antonio Rojas 2022-10-18 20:07:10 UTC

libical bug fixed in 3.0.16

Comment 5 Ricardo J. Barberis 2022-10-19 00:25:29 UTC

Thanks for the info Helmar and Antonio!

I see libical 3.0.16 has landed on my distro among other updates, I'll be checking it out tomorrow.
