Expected results:

The error indicates the function cIB_mapPropsFromICS and I assume that the
problem ist caused by the following line.

This problem seems to be older and yet unfixed.

For comparison. This is the corrected Event.

Comment 1

[Stefan Sitter [:ssitter]]

The example ics is not valid iCalendar event data. In my opinion it cannot be expected that Lightning can parse invalid data. Lightning does one thing it can do: report the invalid event and continue.

Comment 2

[rubbel]

It would be nice to know where the ics data is invalid.
At my laptop I got a error message after I restarted thunderdird.
As guessed it's the ivalid timezone.
But other calendars are more tolerant with the file.
At least thunderbird should ignore the invalid line and continue.
