> (No debugging symbols found in dolphin) Nice of you of using gdb to track this crash down, but in order to have it useful you need to install a few debug symbols packages, here dolphin-dbg and maybe others, `find-dbgsym-packages /usr/bin/dolphin` will help you there. I can refer you to https://wiki.debian.org/HowToGetABacktrace https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Debian What is you dolphin version and debian version ?
