Why would drkonqi run as root?

hello!

if i quote my first comment:

...Attaching to program: /opt/project-neon5/bin/plasmashell, process 2664
Could not attach to process.  If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted....


i believe gdb needs for a root privledge.... but never asks to enter the password... and thats why then gdb doesnt process the error...

maybe im mistaken.... but the message seemed to me that way...


thank you for your reply!

nice day

simon
