Bug#920772: kio-extras: Dolphin mtp:/... stopping data transfer mode on phone crashes kdeinit5



Could be that it is already fixed upstream:
https://cgit.kde.org/kio-extras.git/commit/?id=aaa1edbb74c4fb01affbde7b79bb45d3a9b61f83
 
Also got a slightly different crash:

Application: kdeinit5 (kdeinit5), signal: Segmentation fault

Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
