I don't have those messages launching pulseview from the console but I'm not using sudo to launch it: is there any particular reason why you are using sudo? maybe you should change the permissions of the device you are trying to use (for example with a custom udev rule) instead of launching the program as root.
but I never used pulseview so maybe you can have a better help on this on the official sigrok channels
