-- Information about the crash:
- What I was doing when the application crashed:
I was copying some files from my phone to the computer.
Some transfers got stuck, so I cancelled them.
Then a new transfer was even unable to start, so I have disconnected the phone.
Dolphin crashed shortly afterwards.

The reporter is unsure if this crash is reproducible.

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