Description Mmenzel 2020-04-16 12:12:11 UTC 
Application: dolphin (19.12.3)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 4.15.0-96-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
I tried to resend a file via Bluetooth to a Win10 maschine, but file acceptance was denied by Win10.
The behavior is reproduceable on my KDE NEon maschine (latest updates installed)

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Comment 1 Patrick Silva 2020-04-20 21:41:16 UTC 
Dolphin also crashes on Neon unstable and Arch Linux after failure on sharing by email.

1. right-click on any file > share > send via email...
"Could not find any application or handler for mailto:?attachment=file:///home/yourusername/file.png" error message appears
2, repeat the step 1 with the same file, then Dolphin crashes

It also crashes the second time if there is no error.
openSUSE Leap 15.1 with latest dolphin 20.04.0 and KDE Frameworks 5.69.0 here.
Comment 3 Christoph Feck 2020-05-06 20:55:42 UTC 
I didn't know Dolphin used QML. Is this pulled in via a plugin?
Comment 4 Nate Graham 2020-05-06 23:59:16 UTC 
Ah, the Bluetooth plugin in Purpose uses QML. Sending there
