            Bug ID: 415145
           Summary: AkonadiCalendar can't handle specific
                    RECURRENCE-ID;TZID value
           Product: Akonadi
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general

SUMMARY
Akonadi does not handle vCal events correctly when there's a specific
RECURRENCE-ID;TZID set. I'm using Korganizer & Akonadi with Office365 (EWS) and
in vCal events pulled from there there is RECURRENCE-ID;TZID set and if it's
set to "Europe/Budapest:20191210T100000" Korganizer and konsolecalendar are not
able to show these events at all (konsolecalendar crashes and Korganizer says:
org.kde.pim.akonadicalendar: Can't find any incidence with ui XXX even the
event with that ID exists: I'm even able examine the event using
akonadiconsole).

When I manually remove that RECURRENCE-ID;TZID line from vcal event everything
works normally. And if I set it to RECURRENCE-ID;TZID=Europe/Budapest:20191210
everything works normally. Only if the line continues with that ...T100000
(Europe/Budapest:20191210T100000) this bug appears.

STEPS TO REPRODUCE
1. Create a vCalendar file where is RECURRENCE-ID;TZID with value:
Europe/Budapest:20191210T100000
2. Korganizer does not show these events at all and konsolecalendar crashes
when trying to show this specific event by using --uid argument

EXPECTED RESULT
Events should show up in Korganizer and in konsolecalendar normally.
