This error can be reproduced by opening the atached ics file and trying to save as a Timeline xml file. The ics file contains an event with an empty text.

[Rickard Lindberg]

Should we relax requirement so that we allow empty event texts? Is there a good reason to keep it? We can display a placeholder text if no text has been entered.

[Rickard Lindberg]

Exporting timeline with empty event texts no longer causes an exception.

Also changed event editor to not require a text.
