Operating System: Linux 4.15.0-47-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was copying files of different types (mp3 and png) to internal storage of phone connected with USB, crash happened after some time of programm doing nothing. Have not retried yet. As side effect dolphin does not seem to detect folder into which files were copied.

Comment 1 Julian Steinmann 2019-04-28 18:22:54 UTC

Hello Alexandr, this looks like a problem with the implementation of MTP in Dolphin to me. This implementation has recently been rewritten (for Dolphin 18.12) which brought many improvements to stability and should have fixed crashes similar to yours. Please check if this crash does still happen with Dolphin 18.12 or newer and reopen this report in this case. Thanks!
