Kdev-Valgrind: weird valgrind call

I hope it is correct place to post this

I am a bit confused on how to use valgrind inside kdevelop:
I compiled kdev-valgrind from source using the 5.1 branch (I got
KDevelop 5.1.1 KDE Neon )
The problem is it keeps issuing the following command

/home/max/Projects/Test_projects/testcpp> /usr/bin/valgrind
--tool=callgrind --log-socket= --num-callers=12
--max-stackframe=2000000 --error-limit=yes --cache-sim=no
--branch-sim=no --callgrind-out-file=/tmp/kdevelop.Pu7161
/usr/bin/plasmoidviewer -a .

And I don't understand what plasmoidviewer has to do with it, since the
programm I was trying to valgrind was the following
Did I misunderstood/miss-installed something?
Best regards

#include <stdio.h>
#include <iostream>
#include <unistd.h>

using namespace std;
int main(int argc, char **argv) {
int i=0;
int *j=new int ;
return 0;
