Create a trace log using `export KDE_FORK_SLAVES=true; krusader -d` and entering into compressed files. Add `KRDEBUG` lines, add `KRFUNC` lines code to the code of Krusader, and to the code of the iso and krarc kioslaves, watching what was written to the trace log.
Create trace logs but using `KRDEBUG_BRIEF=true` previously, compare those trace logs, etc.
