Thanks for the bug report. This is a crash in KDirLister from the KIO library. Might be a duplicate of some other smb-related crash reports, but I'm not sure.
I'm not sure if it helps to find the problem, but you could try to reproduce the crash when running inside Valgrind to get some more information: http://community.kde.org/Dolphin/FAQ/Crashes Thanks for your help.
Crash in old unmaintained KF4 software with no duplicates from any Qt5/KF5 versions. If anyone can still reproduce using recent KF5 versions of KIO and Dolphin, please file a new bug. Thanks!
