New crash information added by DrKonqi

korganizer (5.8.1) using Qt 5.11.0

- What I was doing when the application crashed:
Adding a new (a first) event in a manually created ICAL calendar

- Custom settings of the application:
Deleting the default calendar (std.ics) because it didn't appear in calendars list ; creating a new one (in ~/.local/share/apps/korganizer)

Hi everyone,
This problems is solved for me by running /usr/bin/update-mime-database /usr/share/mime and /usr/bin/update-mime-database /usr/kde5/share/mime (as kde5 is installed under /usr/kde5 on my system). So this in not a KDE bug but an installation or distro issue.
