Bug 509376

SUMMARY
I created a journey on my desktop PC by importing a Deutsche Bahn ticket in Itinerary. Sending the journey to my Android phone fails, but with a success message.
I use the Flatpak version of Itinerary.

STEPS TO REPRODUCE
On the PC:
1. Create a new journey
2. Import a DB ticket
3. Open the journey
4. Make sure your phone is connected to the PC through KDE Connect
5. Under "Actions", click "Export…", then "Send to DEVICE XYZ" (whatever your phone is called in KDE Connect)

OBSERVED RESULT
1. In the Itinierary window, a success message appears: "Reise gesendet." in German (Journey sent)
2. At the same time, in Plasma's system tray, an error message appears, coming from KDE Connect: "Die Datei kann nicht geteilt werden" "/tmp/itinerary-YPcwjJ/DtbdFg.itinerary existiert nicht" (translated back to English: "The file cannot be shared"  "/tmp/itinerary-YPcwjJ/DtbdFg.itinerary does not exist"

EXPECTED RESULT
- The journey gets transferred to my (Android) phone.
- Or, if this is a KDE Connect problem, Itinerary does not print a success message and properly reports that sending the file failed.
