--- Comment #10 from kdereport at mailinator.com ---
I don't know how to debug it in drkonqi (to many steps to attach libs in
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/DrKonqi) and it seems
it doesn't work properly.

I run it in gdb:

#dgb dolphin

(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
