SUMMARY
Dolphin dies when (slow or not responding) sshfs filesystem hangs for too long
in Wayland session. Under X11 Dolphin just freeze for certain amount of time,
but does not close.

STEPS TO REPRODUCE
1. Make sure you are running wayland session
2. Connect remote filesystem via sshfs or kdeconnect device bookmark
3. Navigate with Dolphin to some heavy directory located at this filesystem

OBSERVED RESULT
Dolphin print such messages on stdout and quit:

kf.kio.core: UDSEntry for '.' not found, creating a default one. Please fix the
"kio_file" KIO slave
The Wayland connection broke. Did the Wayland compositor die?

EXPECTED RESULT
Dolphin does not close and shows the contents of the directory
