full valgrind output
SUMMARY
running valgrind on plasma-systemmonitor a lot of trouble are showed. this bug
report is to keep trace of them
STEPS TO REPRODUCE
1. build plasma-systemmonitor on your machine
2. create this script: $ cat run.sh
#!/bin/bash
LD_PRELOAD="/home/tom1/kde/build/libksysguard/bin/libFacesPlugin.so
/home/tom1/kde/build/libksysguard/bin/libKSysGuardSensorFaces.so
/home/tom1/kde/build/kconfig/bin/libKF6ConfigCore.so.6 " valgrind
/home/tom1/kde/build/plasma-systemmonitor/bin/plasma-systemmonitor
3. chmod +x && ./run
OBSERVED RESULT
a lot of issue
EXPECTED RESULT
no issue
