-- Information about the crash:
When taking picture from desktop context menu KDE Connect crashes on dismissing camera on phone.
 When selecting take picture option on desktop it brings up a file save dialog, but it doesn't really save any picture if we select a destination path. 
On the phone if I dismiss all the camera window that opens after clicking take picture option by dismissing save file widget. it crashes on desktop

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault
